Task: Answer the multiple choice question.
Question: Which compound has a -27.556% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: C=CCn1c(NCc2c[nH]c3ccccc23)nc2ccccc21
b: CC(Oc1ccc(Br)cc1)C(=O)NC1CCCCCC1
c: Cc1ccc(C)c(OCCCN2CCCC2)c1.O=C(O)C(=O)O
d: O=C(NCCC1CCCCN1S(=O)(=O)c1ccc(Cl)cc1)C(=O)NCCN1CCOCC1
Answer: a. C=CCn1c(NCc2c[nH]c3ccccc23)nc2ccccc21
