Answer:

C. The correlation is due to a third variable: traffic.

Step-by-step explanation:

Correlation shows the strength of the relation between two or more variables.

If increasing the value of first variable, increases the value of the second variable also then it is said to be a positive correlation.

Similarly, If increasing the value of first variable, decreases the value of the second variable then it is said to be a negative correlation.

This question is also related to common sense.

Option A is incorrect as pollution never makes people late for work.

Option B also incorrect because people can have other reasons for there being late.

Option C is correct as there is a large correlation between people late for work and traffic since people might be late because of traffic and also there is a large correlation between traffic and pollution since traffic makes more air and noise pollution. Hence this option is true.

Option D is also incorrect as the third variable doesn't make any sense here.
