If the matrix AB s zero, then

A

It is not necessary that either A=O or B=O

B

A=O or B=O

C

A=O and B=O

D

all the above statements are wrong

Text Solution

Verified by Experts

The correct Answer is:
A

If `{:A=[(1,0),(0,0)],B=[(0,0),(0,1)],"then " AB=[(0,0),(0,0)]:}`
However, `A ne O, B ne O`.
So, option (a) is correct.
