Correct option is C
The correct answer is
(c) Adjective.
• The word “too” is used to modify an adjective/adverb (too hot, too fast, too difficult).
• In the given sentence, “too” comes before “liking”, so “liking” is functioning like an adjective (i.e., describing the dish as not pleasing).
• Therefore, “liking” is used as an adjective here.
Example: The movie was not too exciting.
Why other options are incorrect:
• Noun: a naming word (person/place/thing/idea)
• Verb: an action word (do, write, eat, etc.)
• Adverb: modifies a verb/adjective/adverb (quickly, very, etc.)
