Answer: option a; el peine.
Explanation: the sentence that we have is:
"Which of the following would someone need to arreglarse el peso"
I guess there is a typo in there, and the real sentence says:
"Which of the following would someone need to arreglarse el pelo"
Now, "arreglarse el pelo" means "the air"
So the complete sentence in English says:
Which of the following would someone need to " fix" her hair
Arreglarse means "fix", and when is used in this context, is used as "combing"
The options are:
a) el peine (the airbrush)
b) el maquillaje (the make up)
c) la toalla (the towel)
d) la cita (the date)
The option that is correct here is the airbrush, so the correct option is the option a "el peine"
