Watching cartoons all day/long is bad for/the eyes of childrens.

Correct option is D

Option (d) "the eyes of childrens" contains an error.
Explanation:
The word "childrens" is incorrect because "children" is already a plural noun. It does not take an additional "s." The correct phrase should be "the eyes of children."
Grammatical rule used:
Some nouns, like children, men, women, are already plural and do not require an "s" at the end.
Explanation in Hindi:
"Children" पहले से ही बहुवचन (plural) है, इसलिए "childrens" गलत है। सही वाक्य "the eyes of children" होगा।
