"She is quite tall for her age."

The correct answer is Option (3) → Adverb of Degree

An adverb is a word that tells how, when, where or how much something happens. It can also describe an adjective or another adverb, for example she sings sweetly, very hot.

Here quite goes with the adjective “tall”. It means fairly or more than usual. It tells how tall she is.
