Task: Answer the MCQ question.
Question: Which drug exhibits a 0.131\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CNC(=O)c1csc(-c2ccncc2)n1
b COC(=O)C(NC(=O)c1ccc(C)cc1)(Nc1cccc(C)n1)C(F)(F)F
c Cc1ccc([N+](=O)[O-])cc1N=Cc1ccc(Br)s1
d Nc1ccc(/C=C/c2ccc3ncccc3c2)cc1
Answer: c. Cc1ccc([N+](=O)[O-])cc1N=Cc1ccc(Br)s1
