    no option b is correct .. as T is one one , only zero vector will map to zero vector of range space... no other than zero vector will map to zero..

    A is 4×4 invertable matrix therefore rank of A is 4 or its nullity is zero (nullity= order- rank =4-4=0)so null space contain only zero vector so options B true

    C is not true we know that prodect of eigen values equal to determinate of matrix A. example if egien values 1,1,2,3 then determinate of A is 6 so A is invertable.


    sir just i wanted to ask isn't option b false..?
