Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.680\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(/C=C/c1ccccc1)Nc1cc(S(=O)(=O)N2CCOCC2)ccc1N1CCCC1
b: COc1ccccc1-n1c(SCC(=O)NCC2CCCO2)nc2c([nH]c3ccccc32)c1=O
c: O=C(Cc1ccccc1)NNC(=O)Nc1ccc(Cl)c(Cl)c1
d: CCCCC(=O)Nc1ccc(N2CCN(S(C)(=O)=O)CC2)cc1
Answer: c. O=C(Cc1ccccc1)NNC(=O)Nc1ccc(Cl)c(Cl)c1
