I'm thinking B because my implies that the person possesses that thing. My bicycle. He is in possession of the bike
Umm i have no idea either please help us
Sorry what is your question I got confuse you want to now if they are synonymous
The correct answer is B, 'compound-complex sentence', because this particular sentence consists of two independent clauses ('gracefully, the dancer took a bow) and ((the dancer) smiled) and one dependent clause (before she left the stage), which is the definition of a compound-complex sentence.
The one you have selected is the correct answer.
