Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.121\% 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 additional words.
Options:
a: COc1cc(C)c(CNC2CCCCC2)cc1C
b: O=C(N/N=C\c1ccc(COc2ccc([N+](=O)[O-])cc2)o1)c1ccccc1Cl
c: Cc1cccc(NS(=O)(=O)c2cc(C(=O)N3CCCC3)ccc2Cl)c1
d: CCCCOC(=O)Nc1ccc(C(=O)OCCC)cc1
Answer: c. Cc1cccc(NS(=O)(=O)c2cc(C(=O)N3CCCC3)ccc2Cl)c1
