Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.146\% 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) O=C(COc1ncnc2ccccc12)NCCc1ccccc1
(b) Cc1cc[n+](C(C)C(=O)c2ccc(-c3ccccc3)cc2)cc1.[Br-]
(c) CCc1c(C)sc(NC(=O)c2ccco2)c1C(=O)N1CCCCC1
(d) COc1cc(/C=C/C(=O)O)cc(S(=O)(=O)NCCCO)c1OC
Answer: c. CCc1c(C)sc(NC(=O)c2ccco2)c1C(=O)N1CCCCC1
