Answer:
(a)First Row, First Column =1
(b)First Row, second Column =0
(c)Second Row, First Column =0
(d)Second Row, second Column =1
Step-by-step explanation:
Given matrix 
The Inverse of a 2X2 matrix

can be found using the following:

Therefore:

Next, we find the product 

Therefore:
(a)First Row, First Column =1
(b)First Row, second Column =0
(c)Second Row, First Column =0
(d)Second Row, second Column =1
NOTE: The multiplication of a matrix and its inverse always gives the identity matrix as seen above,
