Solution

The correct option is D B has twice as many elements as C
Since, A is the determinant of order 3 with entries 0 or 1 only.
Also, B is the subset of A consisting of all determinants with value 1.
[since, if we interchange any two rows or columns, then among themself sign changes]
Given, C is the subset having determinant with value -1.
B has many elements as C.
