Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.505\% 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) CCOC(=O)c1c(NC(=O)Nc2ccccc2)sc(C)c1C
(b) CC1CCC(NCCNC(=O)c2ccco2)CC1
(c) O=C(c1ccccc1)c1cc([N+](=O)[O-])ccc1N1CCOCC1
Answer: a. CCOC(=O)c1c(NC(=O)Nc2ccccc2)sc(C)c1C
