MCQ
Which of the following is correct?
  • 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 $D$.
