Task: Answer the multiple choice question.
Question: Which compound has a 9.671\% 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 other words.
Options:
(a) COc1ccc(S(=O)(=O)N2CCOCC2)cc1NC(=O)c1ccc(OCC(C)C)c(OC)c1
(b) Cc1cccc(NC(=S)N2CCC(C(=O)c3ccc(F)cc3)CC2)c1C
(c) O=C(NNC(=O)C1CCCCC1)c1ccncc1
(d) Cc1cc(CNC(=O)Cc2ccccc2F)c2ccccc2n1
Answer: c. O=C(NNC(=O)C1CCCCC1)c1ccncc1
