Respuesta :
D. - among the weeping willows, because it begins with a preposition (among)
The correct option is d. among the weeping willows.
A prepositional phrase begins with a preposition and ends with a noun, pronoun or noun phrase.
In this case, "among the weeping willows" starts with the preposition "among" and ends with the noun phrase "the weeping willows".
The other options given do not start with a prepostition. Option A starts with the conjunction "that". Option B is part of the verb phrase and option C is a noun phrase.
