(b) False

The question was asked in a national level competition.

I need to ask this question from Recursion in division Recursion of Data Structures & Algorithms II

Answer 1

Correct answer is (a) True

The explanation is: Given that B=C, so the two matrix can be recursively multiplied. Therefore, the order of the Matrix X*Y is A*D.
