As for this problem, the most probable and the most likely answer for this would be D. my father drove me to the field where the team practices.
On the first option, I told my parents I wanted to play on the softball team this year, there isn't an adverb clause to be found. On the second option, do you play on any of the local sports teams, there isn't an adverb clause to be found, too. On the third option, I believe the team practices on Monday and Thursday afternoons, there isn't an adverb clause to be found again. On the last option, my father drove me to the field where the team practices, the adverb clause would be where the team practices.
