Which of the following can be Bronsted-Lowry acids

Can someone tell me if I chose correctly, out of the 6 choices given I chose A, and E
A. H2O
B.I-
C.HOCl
D.FeBr3
E.CH3CH2COOH
F. CO2

Bronsted-Lowry acids are proton donors. So, if a compound doesn't have a proton, it cannot be a Bronsted-Lowry acid. (Now, you have to be careful, because a lot of compounds have protons, but can't give them to something else, but that's not a problem in this question.)

So, A, C and E are all Bronsted-Lowry acids. C is hypochlorous acid.
