Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 16.438\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C1C(=O)N(CCCn2ccnc2)C(c2ccc(Br)cc2)/C1=C(\O)c1ccc2c(c1)OCCO2
b: CCCC(=O)NCCCCNC(=O)CCC
Answer: a. O=C1C(=O)N(CCCn2ccnc2)C(c2ccc(Br)cc2)/C1=C(\O)c1ccc2c(c1)OCCO2
