The correct answer is A) al banco
Explanation:
The sentence presented requires a place to be completed; indeed, the four options presented refer to different places as "banco" means "bank", "parque" means "park", "museo" means "museum" and "centro" means center (you can guess the meaning based on the similarity of words).
This implies you need to understand the situation presented to match this with the correct place. In this way, the word "dinero" in "Cuando necesitas el dinero" is essential to find the answer because "dinero" refers to coins, banknotes and similar; thus, "dinero" is equivalent to "money" and this is related to "al banco". Also, when "necesitas dinero" or "you need money" the place you need to go to is a bank. According to this, the correct answer is "Cuando necesitas el dinero, vas al banco" that in English means "when you need money, you go to the bank".
