Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -14.734\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C(COc1cccnc1[N+](=O)[O-])c1ccc(Cl)s1
[b] Cc1cc2c(cc1S(=O)(=O)N(C)Cc1ccccc1)n(C)c(=O)c(=O)n2C
[c] C=CCSC(=C(C#N)C#N)c1cc2c([nH]1)CCCC2
Answer: b. Cc1cc2c(cc1S(=O)(=O)N(C)Cc1ccccc1)n(C)c(=O)c(=O)n2C
