Match the following:

To solve the problem, we need to correctly match the types of epithelium with their respective examples.
1. Understanding the Epithelium Types:
The epithelium types are:
2. Analyzing the Correct Pairing:
The correct pairings based on the examples are:
A (Simple squamous) = V (Pericardium)
B (Simple cuboidal) = I (Germinal epithelium)
C (Stratified non-keratinised) = IV (Vagina)
D (Transitional) = II (Wall of urinary bladder)
Final Answer:
The correct option is (B) A - V, B - I, C - IV, D - II.
Match the following:

Assertion: The male ants are developed by parthenogenesis from unfertilized eggs.
Reason: The sex of offspring depends on the type of sperm that fertilizes the ovum, which is not relevant since male ants develop through haploid parthenogenesis, which does not involve fertilization.
Two concentric thin circular rings of radii 50 cm and 40 cm each, carry a current of 3.5 A in opposite directions. If the two rings are coplanar, the net magnetic field due to the two rings at their centre is:
