Question:

Match List I with List II

List I List II
A. $\begin{bmatrix}2 & 3 & 0\\1 & 1 & -2\end{bmatrix}$ I. null matrix
B. $\begin{bmatrix}0 & 0\end{bmatrix}$ II. $2×3$ matrix
C. $\begin{bmatrix}2& 2\\3 & 0\end{bmatrix}$ III. $3×2$ matrix
D. $\begin{bmatrix}1 & 0\\-1& -1\\0 & 3\end{bmatrix}$ IV. square matrix

Choose the correct answer from the options given below :

Options:

A-III, B-II, C-IV, D-I

A-III, B-I, C-IV, D-II

A-II, B-I, C-IV, D-III

A-II, B-IV, C-I, D-III

Correct Answer:

A-II, B-I, C-IV, D-III

Explanation:

The correct answer is Option (3) → A-II, B-I, C-IV, D-III

(A) $\begin{bmatrix}2 & 3 & 0\\1 & 1 & -2\end{bmatrix}$ → Order = 2 × 3

(B) $\begin{bmatrix}0 & 0\end{bmatrix}$ → Null Matrix (Each element are zero)

(C) $\begin{bmatrix}2& 2\\3 & 0\end{bmatrix}$ → Square Matrix (Rows = Column = n)

(D) $\begin{bmatrix}1 & 0\\-1& -1\\0 & 3\end{bmatrix}$ → Order = 3 × 2
