Answer:

The correct option is C.

Explanation:

r-values represents correlation between two variables. The r-value lies from -1 to 1.

If r=-1 or close to -1, then it represents strong negative correlation.

If -1 < r < 0 or close to -0.5, then it represents weak negative correlation.

If r=0 or near to 0, then it represents no correlation.

If 0 < r < 1 or close to 0.5, then it represents weak positive correlation.

If r=1 or close to 1, then it represents strong positive correlation.

The given r values are -0.75, -0.55, -0.15 and -0.35.

From these r-values, -0.15 represents the weakest correlation because it is nearest to 0.

Therefore the correct option is C.
