True or False : If A and B are square matrices of the same order then AB is non-singular if and only if both A and B are non-singular.

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : Current and time both have direction as well as magnitude but still are not considered vector Reason : They do not follows laws of vector addition

True or False statements : if A and B are square matrices of the same order then A - B = B - A.
