yeah its me again :) and thank you Writeacher for checking my answer on smoking

An antihistamine used to treat a common cold is intended to:
A. Decongest
B. Suppress the cough reflex
C. Dry secretions
D. Increase mucus clearance

I think it could be either A or D but I'm thinking maybe A is the best answer.

I vote for C. Read this site about antihistamines.
