The hall was __________ decorated with flowers and soft lights.

The correct answer is Option (2) → tastefully

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.

Complete sentence: The hall was tastefully decorated with flowers and soft lights. The blank comes before “decorated” and tells how the hall was decorated, so it needs an adverb.
