Choose the correct answer from the options given below :
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(II). (B)-(IV),(C)-(III), (D)-(I)
(A) Diagonal Matrix → $\begin{bmatrix}1 & 0 & 0 \\0 & 2 & 0\\0 & 0 & 3\end{bmatrix}$
(B) Scalar Matrix → $\begin{bmatrix}5 & 0 & 0 \\0 & 5 & 0\\0 & 0 & 5\end{bmatrix}$ [$a_{ij}=c|i=j|$, c → constant]
(C) Square Matrix → $\begin{bmatrix}2 & 4\\3 & 5\end{bmatrix}$
(D) Identity Matrix → $\begin{bmatrix}1 & 0 & 0 \\0 & 1 & 0\\0 & 0 & 1\end{bmatrix}$
