Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.985\% human ether-à-go-go related gene (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 other words.
Options:
[a] COc1ccc(C)cc1N(CC(=O)N1CCCCCC1)S(=O)(=O)c1ccc(C)cc1
[b] O=C(CNS(=O)(=O)c1ccc2ccccc2c1)OCc1csc(-c2ccccc2)n1
[c] COc1ccc(CNn2c(-c3cccs3)nc3ccccc3c2=O)cc1OC
[d] COc1ccccc1NCc1ccc([N+](=O)[O-])s1
Answer: c. COc1ccc(CNn2c(-c3cccs3)nc3ccccc3c2=O)cc1OC
