If A = [1] , then A is : - Vidyadip

MCQ

If $A = [1] ,$ then $A$ is :

A
Zero matrix
B
SIngular matrix
✓
Non $-$ singular matrix
D
Data insufficient

✓

Answer

Correct option: C.

Non $-$ singular matrix

$\text{A} = \big[1\big] $ is an identity matrix with order $1\times1.|\text{A}|\neq0$
So $A$ is nonsingular.
