Step-by-step explanation:

Response:

The correct option is: C.

C. {(-2, 4), (-1, 2), (0, 0), (1, -2)}

Detailed explanation:

A strong negative correlation is present--

In this context, a negative correlation signifies that as one variable increases, the other decreases, and vice versa.

This indicates an inverse relationship between the two variables.

Furthermore, this relationship is considered strong if the data points cluster above the line of best fit.

Thus, the data set illustrating a robust negative correlation is:

C. {(-2, 4), (-1, 2), (0, 0), (1, -2)}

In this scenario, the x-values increase consistently by 1 (i.e., -2, -1, 0, 1), while the corresponding values decrease steadily by 2 (i.e., 4, 2, 0, -2).

As a result, a linear correlation emerges with all points positioned above the line, and the line of best fit exhibits a negative slope.

Thus, the data shows a strong negative correlation.
