Task: Answer the multiple choice question.
Query: Which drug has a 16.901\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CC1=C(C(=O)Nc2ccccc2)C2(CCCCC2)C(C#N)=C(S)N1
b Cc1ccc(-c2ccc(/C=N/N3C(=O)C4C5C=CC(C6CC56)C4C3=O)o2)c([N+](=O)[O-])c1
c Nc1ccc(NC(=O)c2cccs2)cc1
d O=C(NCc1cccc(F)c1)C1CCC(=O)N(CCc2cccc(F)c2)C1
e CCOC(=O)C1=C(C(F)(F)F)Nc2ncnn2C1c1cc(OC)c(OC)cc1OC
Answer: c. Nc1ccc(NC(=O)c2cccs2)cc1
