MCQ
If a matrix has 4 elements, then the order of the matrix not possible is:
  • A
    $2 \times 2$
  • B
    $1 \times 4$
  • ✓
    $2 \times 3$
  • D
    $4 \times 1$
✓

Answer

Correct option: C.
$2 \times 3$
(c) $2 \times 3$
Explanation:
If a matrix has $p$ elements, then the order $m \times n$ of the matrix must be such that $m \times n=p$.
So, out of the given options, $2 \times 3 \neq 4$.
