Hello mate!

You are studying the relationship between levels of job stress and measures of job efficiency.

now, we want to describe a positive correlation.

A correlation between two quantities, A and B, is A = kB

where k is a constant.

If the correlation is positive, means that when A increases also increase B, and then k is a positive number.

This means that, in our case,  when job stress increases, job efficiency also increases.

Then the right answer is A "As stress levels increase, job efficiency increases."
