Let A be a 2×2 matrix with real entries. Let l be the 2×2 identity matrix. Tr(A) denotes the sum of diagonal entries of A. Assume that A2=I
Statement I: If A≠I and A≠−I then det‌A=−1
Statement II: If A≠I and A≠−I then Tr A≠0

Statement I is true, statement II is true; statement II is a correct explanation for statement I
Statement I is true, statement II is true; statement II is not a correct explanation for statement I
Statement I is true, statement II is false
