If (P ) and (Q ) are two non-zero square matrices of the same order such that the product (P Q=0 ), then ........

Options

  1. AExactly one of them must be singular
  2. BBoth (P ) and (Q ) must be singular
  3. CBoth (P ) and (Q ) must be non-singular
  4. DNone of the options are correct

Correct answer

D. None of the options are correct

Step-by-step solution

For 2-non zero square matrix; of same order; product may be zero even when matrices are singular or non singular. So none of the options is correct.
