Task: Answer the multiple choice question.
Query: Which compound has a 8.803\% 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 other words.
Options:
a: O=C1CCC2=C(CCCC2=O)N1
b: COC(=O)C1=C(c2ccccc2)C[C@@H]2CC[C@H]1N2C(=O)N1CCCCC1
c: COc1ccc(CN(C(=O)c2ccc(-c3ccccc3)[nH]2)C(C(=O)NCC2CCCO2)c2ccc(C)o2)cc1
Answer: a. O=C1CCC2=C(CCCC2=O)N1
