Given Problem -

Let A, B, C be square matrices. Prove the following statements: (a) If A is similar to B and B is similar to C, then A is similar to C. (b) If A is similar to B then for every j Co(A) we have rank((A - Ajl)") = rank((B - AjI)") for r = 1, 2, ...,n. (c) If A is skew-hermitian then all eigenvalues of A are pure imaginary. (d) If A is unitary, then all eigenvalues of A have absolute value one
