Correct option is A
Correct Answer: (a) A
Error: "The doctor careful examined the patient"
Grammatical Rule Applied:
· Adverb Usage: The word "careful" is an adjective, but it should modify the verb "examined", which requires an adverb instead of an adjective.
· The correct adverbial form of "careful" is "carefully" because adverbs modify verbs and describe the manner in which an action is performed.
Corrected Sentence:
"The doctor carefully examined the patient and prescribed the necessary medication for a speedy recovery."
