Choose the part of the sentence that contains an error:
The child is afraid from the dark.

Correct option is D

Option (d) contains an error.
Detailed explanation of error: The adjective “afraid” takes the preposition “of”, not “from.” The correct collocation is “afraid of + noun/gerund.” Hence, the sentence should read: “The child is afraid of the dark.”
Grammatical rule used: Certain adjectives require fixed prepositions (adjective–preposition collocations), e.g., afraid of, interested in, good at.
Example: She is afraid of spiders. / He is interested in astronomy.
Information booster / exceptions:
· afraid for someone = concerned about their safety/well-being (e.g., I was afraid for the child in the storm.)
· frightened by/at can be used with different prepositional nuances (e.g., frightened by the noise; frightened at the sight). “Afraid from” is non-standard.
