Step 1: Understanding the Concept: 
The question asks to arrange four key figures associated with the Bengal School of Art in chronological order based on their birth dates. 
 
Step 3: Detailed Explanation: 
To establish the correct order, we need to know the birth year of each individual: 
(C) E. B. Havell: Ernest Binfield Havell, the British art administrator who promoted the Bengal School, was born in 1861. 
(B) Abanindranath Tagore: The founder of the Bengal School, was born in 1871. 
(D) Kshitindranath Majumdar: A prominent student of Abanindranath Tagore and a key artist of the Bengal School, was born in 1891. 
(A) Abdul Rehman Chughtai: An artist associated with the Bengal School style, was born in 1897 (some sources say 1899). 
Arranging them from the earliest to the latest birth year gives the sequence: E. B. Havell$\rightarrow$Abanindranath Tagore$\rightarrow$Kshitindranath Majumdar$\rightarrow$Abdul Rehman Chughtai. This corresponds to the order (C), (B), (D), (A). 
 
Step 4: Final Answer: 
Based on their birth years, the correct chronological order is (C) E. B. Havell, (B) Abanindranath Tagore, (D) Kshitindranath Majumdar, (A) Abdul Rehman Chughtai.
