Your question is not clear and seems to be incomplete.
I think the question is matrix of order 2 and elements are 0,1
then
no. of possibilities of matrix of order 2 are 2*2*2*2=16
if the elements of matrix are a,b,c,d
then determinant of matrix is ad-bc
given ad-bc>0
so a=1,d=1 and b,c should not be equal to 1 simultaneously
so no. of favourable cases are 3
hence probability is 3/16 and D is the correct answer.
