Task: Answer the multiple-choice question.
Query: Which drug exhibits a -18.081\% 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, or c without using any other words.
Options:
[a] COCCNC(=S)Nc1ccc(S(=O)(=O)Nc2cnc3ccccc3n2)cc1
[b] O=C(Cn1cnc2ccccc2c1=O)NNC(=O)c1cccc([N+](=O)[O-])c1
[c] CCOC(=O)C1(CCCc2ccccc2)CCN(C(=O)c2cncs2)CC1
Answer: c. CCOC(=O)C1(CCCc2ccccc2)CCN(C(=O)c2cncs2)CC1
