Solution and Explanation
Name the type of isomerism exhibited and draw isomers:
(I) [Co(NH3)6][Cr(CN)6]
Solution: This shows ionization isomerism.
Isomer: [Co(CN)6][Cr(NH3)6]
(II) [Co(en)3]3+
Solution: This shows optical isomerism due to chirality from en ligands.
Isomers: d- and l- forms (non-superimposable mirror images).
(III) [Co(NH3)3(NO2)3]
Solution: This compound exhibits geometrical isomerism, as the arrangement of ligands around the metal ion can vary. The two possible isomers are cis- and trans- configurations.

The Anguish of the King
When the king Devanampiya Piyadassi had been ruling for eight years, the (country of the) Kalingas (present-day coastal Orissa) was conquered by (him). One hundred and fifty thousand men were deported, a hundred thousand were killed, and many more died.
After that, now that (the country of) the Kalingas has been taken, Devanampiya (is devoted) to an intense study of Dhamma, to the love of Dhamma, and to instructing (the people) in Dhamma.
This is the repentance of Devanampiya on account of his conquest of the (country of the) Kalingas.
For this is considered very painful and deplorable by Devanampiya that, while one is conquering an unconquered (country) slaughter, death and deportation of people (take place) there...- CBSE CLASS XII - 2025

Declining a Royal Gift
This excerpt from a sufi text describes the proceedings at Shaikh Nizamuddin Auliya’s hospice in 1313 : I (the author, Amir Hasan Sijzi) had the good fortune of kissing his (Shaikh Nizamuddin Auliya’s) feet ... At this time a local ruler had sent him the deed of ownership to two gardens and much land, along with the provisions and tools for their maintenance. The ruler had also made it clear that he was relinquishing all his rights to both the gardens and land. The master ... had not accepted that gift. Instead, he had lamented: “What have I to do with gardens and fields and lands ? ... None of our ... spiritual masters had engaged in such activity.”
Then he told an appropriate story: “... Sultan Ghiyasuddin, who at that time was still known as Ulugh Khan, came to visit Shaikh Fariduddin (and) offered some money and ownership deeds for four villages to the Shaikh, the money being for the benefit of the dervishes (sufis), and the land for his use. Smiling, Shaikh al Islam (Fariduddin) said: ‘Give me the money. I will dispense it to the dervishes. But as for those land deeds, keep them. There are many who long for them. Give them away to such persons.’”- CBSE CLASS XII - 2025

What taluqdars thought
The attitude of the taluqdars was best expressed by Hanwant Singh, the Raja of Kalakankar, near Rae Bareli. During the mutiny, Hanwant Singh had given shelter to a British officer, and conveyed him to safety. While taking leave of the officer, Hanwant Singh told him:
Sahib, your countrymen came into this country and drove out our King. You sent your officers round the districts to examine the titles to the estates. At one blow you took from me lands which from time immemorial had been in my family. I submitted. Suddenly misfortune fell upon you. The people of the land rose against you. You came to me whom you had despoiled. I have saved you. But now – now I march at the head of my retainers to Lucknow to try and drive you from the country.- CBSE CLASS XII - 2025
