Hello there!
Greetings!
To solve these kind of questions you should always remember that if A and B are matrices then rank of AB is always less than or equal to rank of matrix A . And if the matrix B is a non -singular matrix then rank of AB is equal to A . So in case if B is a non -singular matrix then rank of (AB)= rank(A)=2 (given).
Thankyou
