Answer:

d.The parents of a teenager with a time limit are more likely to usually monitor the screen time than to always monitor it.

Step-by-step explanation:

The table tells us the percentages of each column (notice they add up to 1).  But it does not tell us what percent of kids have a time limit and what percent don't.  In other words, we can compare two values within the same column, but we can't compare the two columns to each other.

Options a, b, and c all compare time limit to no time limit.

Only option d compares two values in the same column.

Answer:

Option (D) The parents of a teenager with a time limit are more likely to usually monitor the screen time than to always monitor it.

Step-by-step explanation:

29% of the parents of teenagers with a time limit usually monitor the screen time, while only 11% always monitor it.
