Explanation:

Step1: Recall correlation concept

The strength of a linear - relationship is determined by the absolute value of the correlation coefficient. The closer the absolute value of the correlation coefficient is to 1, the stronger the linear relationship.

Step2: Compare absolute values

We have the following correlation coefficients:

  • Internet users and Social network users: $|0.298|$
  • Internet users and Broadband subscribers: $|0.974|$
  • Internet users and Population: $|0.832|$
  • Social network users and Broadband subscribers: $|0.286|$
  • Social network users and Population: $|0.238|$
  • Broadband subscribers and Population: $|0.704|$

The largest absolute - value is $0.974$, which is the correlation between Internet users and Broadband subscribers.

Answer:

F. Internet users and Broadband subscribers
