Task: Answer the multiple-choice question.
Query: Which drug has a -1.794\% 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 other words.
Options:
a: COc1ccc(NS(=O)(=O)c2ccc(-n3nnc4ccccc43)c([N+](=O)[O-])c2)cc1
b: CCCN(C1CCS(=O)(=O)C1)S(=O)(=O)c1cc(OC)ccc1OC
c: O=C1CC(c2ccccc2)CC(O)=C1C=NCc1ccco1
d: Cc1ccc(CCNC(=O)Cn2ccc3cc(S(=O)(=O)N4CCCC4)ccc32)cc1
Answer: c. O=C1CC(c2ccccc2)CC(O)=C1C=NCc1ccco1
