Task: Answer the multiple choice question.
Question: Which compound has a -4.237\% 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 CN(Cc1ccccc1)c1oc(COc2ccccc2F)nc1C#N
b Cc1nn2c(N3CCN(C4CCCC4)CC3)cc(C(C)(C)C)nc2c1-c1ccccc1
c O=C(/C=C\Nc1ccccn1)c1ccc(Cl)cc1
Answer: a. CN(Cc1ccccc1)c1oc(COc2ccccc2F)nc1C#N
