If a matrix has 12 elements, then the possible orders it can have, are
(A) \(1 \times 12\)
(B) \(4 \times 3\)
(C) \(6 \times 3\)
(D) \(6 \times 2\)
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A), (B) and (D) only
A matrix of order m × n has mn elements, so a possible order needs mn = 12.
Checking the statements
(A) \(1 \times 12\) — Correct. \(1 \times 12 = 12\).
(B) \(4 \times 3\) — Correct. \(4 \times 3 = 12\).
(C) \(6 \times 3\) — Incorrect. \(6 \times 3 = 18\), not 12.
(D) \(6 \times 2\) — Correct. \(6 \times 2 = 12\).
