A matrix that is not square has a determinant that is:
AAlways one
BAlways two
CNot defined
DAlways zero
Answer & Solution
Correct answer: C. Not defined
1. Determinants are defined only for square matrices.
2. A rectangular matrix falls outside that definition.
3. So its determinant is not defined at all.
