The correct answer is:

a strong negative correlation

Explanation:

A strong correlation is one that is close to either 1 or -1. -0.93 is very close to -1, so this is a strong correlation.

A negative correlation is one that has a negative r-value. This is a negative r-value, so it is a negative correlation.
