Task: Answer the multiple choice question.
Question: Which compound exhibits a -2.361% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(CN1CCN(c2ccccn2)CC1)NC1CCCC1
b: COc1ccccc1CC(=O)NC12CC3CC(CC(C3)C1)C2
c: CSCCC(C(=O)N(C)CC(=O)Nc1cccc(F)c1)N1C(=O)c2ccccc2C1=O
Answer: a. O=C(CN1CCN(c2ccccn2)CC1)NC1CCCC1
