Correct option is B
As per the provisions of the Indian Income Tax Act, the children education allowance is exempted up to ₹100 per month per child, for a maximum of two children. In the given scenario, the allowance for three children is ₹240 per month. Since the exemption is limited to ₹100 per child per month, the exempted amount would be: 2 children x ₹100 per child per month = ₹200 per month. Therefore, the correct answer is: B. ₹160 p.m.
