If matrix satisfies , which condition MUST hold?

Answer and explanation

Correct answer: A. Trace(M) = 0 and Det(M) = 0

  1. Step 1: By the Cayley-Hamilton theorem: . Step 2. If , then . Step 3. Then . For non-zero nilpotent matrices, this requires . Answer: Trace(M) = 0 and Det(M) = 0. Why not the others: Nilpotent matrices have zero trace and zero determinant.
