The correct answer is Option (3) → swiftly
"Rahul drove his car _____ to reach Delhi soon" is "swiftly."
Explanation:
"Fastly" is not a standard adverb; the correct form is "fast."
"Fluently" is an adverb used to describe how someone speaks a language smoothly and accurately; it doesn't fit the context of driving a car.
"Firmly" is an adverb that describes how something is done with strength or determination, which is not appropriate in the context of driving a car.
"Swiftly" is the correct adverb here because it means moving quickly and efficiently, which fits the context of Rahul wanting to reach Delhi soon. |
