Step-by-step explanation:

We given with

We have to find Element in row 1 and column 1 of Matrix C.

Matrix C is Matrix X.

So, we have

So first we find inverse of first matrix,

Inverse of matrix A is given by

let,

then,

|A| = 4 × 1 - 0 × y = 4

So,

Element at row 1 and column 1 of matrix is

Therefore, Option A is correct.
