Answer:

D. i

Step-by-step explanation:

When putting i to a power, there is a rule.

i¹ = i

i² = -1

i³ = -i

i⁴ = 1

And it repeats again, such as:

i⁵ = i

i⁶ = -1

And so forth.

This rule also applies to -i, but the values are slightly different:

(-i)¹ = -i

(-i)² = -1

(-i)³ = i

(-i)⁴ = 1

And that one keeps repeating such as

(-i)⁵ = -i

(-i)⁶ = -1

And so forth.

So to answer your question, (-i)³ = i.
