B
18
C
27
D
512

Solution

## The correct option is D $$512$$The number of possible entries of $$3\times 3$$ matrix is $$9$$.Every entry has two choices, $$0$$ or $$1$$Thus, total number of choices is$$2\times 2\times 2\times 2\times 2\times 2\times 2\times 2\times 2=2^9=512$$Hence, the correct option is D. $$512$$.Mathematics
