Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.353\% 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: COc1ccc(CC(C)NCCc2ccc(OC)c(OC)c2)cc1
b: O=C(Nc1ccc2c(c1)OC1(CCCC1)O2)C1CC1
c: CCCCNC(=O)C1CC(=O)N(CCc2ccc(C)cc2)C1
Answer: b. O=C(Nc1ccc2c(c1)OC1(CCCC1)O2)C1CC1
