A statement is given followed by two assumptions numbered I and II. You have to assume everything in the statement to be true and decide which of the assumptions is/are implicit in the statement.

Statement:

Children below we age of 5 years should not be allowed too much of screen time a day.

Assumptions:

I. Too much screen time for growing children will affect them adversely.

II. Limited screen time is not detrimental to children below 5 years of age.

"Children below the age of 5 years should not be allowed too much screen time a day."

Assumption I:

"Too much screen time for growing children will affect them adversely."

This is implicit.
If the statement advises against excessive screen time, it is based on the assumption that too much screen time can have adverse effects on children below 5 years of age.

Assumption II:
"Limited screen time is not detrimental to children below 5 years of age."

This is also implicit.
If the recommendation is for limiting screen time, it assumes that limited screen time is acceptable and not harmful to young children.

Thus, correct option is (d).
