For which integers n is the equality (-2)ⁿ = -2ⁿ true? Select the best answer and justify by parity reasoning.

For all integers n, because parentheses do not affect the sign.

For all odd integers n, because an odd exponent leaves the negative sign unpaired so (-2)ⁿ equals -2ⁿ.

For no integers n, because -2ⁿ and (-2)ⁿ are never equal.

For all even integers n, because even exponents always produce negative results for negative bases.
