Consider the set of all determinants of order with entries or only. Let B be the subset of consisting of all determinants with value . Let be the subset of consisting of all determinants with value . Then
has as many elements as
Explanation for the correct options:
Given,
Set of all determinants of order with entries or only.
Let be the subset of consisting of all determinants with value .
be the subset of consisting of all determinants with value .
By interchanging any rows or columns then sign of the determinant will change.
Therefore,
The number of elements of is equal to the number of elements in
Hence, option (B) is the correct answer
