Question

¿Dónde está mi bolígrafo?

Answer 1

A) En escritorio. It’s asking where your pen is. You’re responding as it’s on your desk.

Answer 2

A. En tu escritorio (translates to "in your desk")

REASON: answer choice B is saying "in the door" which makes no sense. Answer choice C is saying "in the window" which also makes no sense, and answer choice D is saying "in your watch". Since answer choices B,C, and D make no sense the answer has to be A which is the answer that makes the most sense. 

I'm in Spanish 2 :)
