The matrix `P=[{:(0,0,4),(0,4,0),(4,0,0):}]` is a

A

square matrix

B

diagonal matrix

C

unit matrix

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
We know that, in a square matrix number of rows are equal to the number of columns. So the matrix `P=[{:(0,0,4),(0,4,0),(4,0,0):}]` is a square matrix.
