MCQ

A
Determinant is a square matrix.
B
Determinant is a number associated to a matrix.
C
None of these.
✓
Determinant is a number associated to a square matrix.

✓

Answer

Correct option: D.

Determinant is a number associated to a square matrix.

d
We know that to every square matrix, $A=[\text { aij }]$ of order $n .$ We can associate a number called the determinant of square matrix $A$, where $a i j=(i, j)^{\text {th }}$ element of $A$.

Thus, the determinant is a number associated to a square matrix.

Hence, the correct answer is $D$.
