Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.516\% 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 additional words.
Options:
(a) CCc1c(C)nc2ncnn2c1N1CCCC(C(=O)NCc2ccc3c(c2)OCO3)C1
(b) CCn1c(SCC(=O)NCCOC)nc2sc3c(c2c1=O)CCCC3
(c) COCCN1CC(C(=O)NCc2ncccc2C)CCC1=O
Answer: c. COCCN1CC(C(=O)NCc2ncccc2C)CCC1=O
