Answer:
HCl
Explanation:
Some easy ways to identify if a compound is an acid is to locate an H+ proton, while basic compounds will have an OH- ion.
Examine all the choices:
A) NaOH
Already, we see that OH is here, so it's a base, not an acid. Eliminate.
B) NaCl
This doesn't have an H+ or an OH-, so it's not an acid. It's actually a salt. Eliminate.
C) HCl
This does have an H+, so it's an acid.
D) 
Although this does have an H, it's a hydrocarbon - an organic compound. So, it's not an acid.
The answer is thus C.
