Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 12.808\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc(CC(=O)OCc2cc(=O)n3cc(Br)ccc3n2)cc1OC
(b) O=S(=O)(c1ccccc1)[C@@]1(c2ccccc2)C[C@@H]2ON=C(c3cccc(-c4ccccc4)c3)[C@@H]2C1
(c) O=c1[nH]c2c(c3c1CCCC3)CCCC2
Answer: c. O=c1[nH]c2c(c3c1CCCC3)CCCC2
