Which phrase best describes the tone of this sentence? A. Arrogant and flowery B. Lighthearted and cheerful C. Silly and childish D. Poetic and meaningful

Where’s the phrase?

The sentence Shelby flittered around the room chatting with old friends and making new ones like she was a butterfly dancing on the expectant winds of spring is B. lightheaded and cheerful.

It is definitely not arrogant - there are only positive feelings in the sentence. C is also incorrect because the word childish has a negative connotation. Option D is incorrect because the sentence isn't really that meaningful.

This leaves us with B - obviously the sentence is cheerful, mentioning butterflies and fluttering wings. It is also not serious, thus lightheaded.
