Write the name of the square matrix `A=a_(ij)` in which `a_(ij)=0`,`i!=j`,

The square matrix A=[a_(ij)" given by "a_(ij)=(i-j)^3 , is a

In square matrix A=(a_(ij)) if i lt j and a_(ij)=0 then A is

A square matrix A=[a_(ij)] in which a_(ij)=0 for i!=j and [a]_(ij)=k (constant) for i=j is called a (A) unit matrix (B) scalar matrix (C) null matrix (D) diagonal matrix
