Task: Answer the multiple-choice question.
Query: Which compound has a 12.286\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=c1ccc2ccc(Oc3ccc(Cl)cc3[N+](=O)[O-])cc2o1
b: Cc1ccccc1C(=O)NNC(=O)c1ccncc1
c: O=Cc1ccccc1OCCOc1ccccc1C=O
d: CC1CCCCN1C(=O)CNCc1ccc(F)cc1.O=C(O)C(=O)O
e: O=C(O)/C=C/c1coc2ccc(F)cc2c1=O
Answer: a. O=c1ccc2ccc(Oc3ccc(Cl)cc3[N+](=O)[O-])cc2o1
