Problem statement: Answer the multiple choice question.
Query: Which compound has a 16.250\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(/C(C=Nc1cccc(C(F)(F)F)c1)=C(/O)c1ccco1)C(F)(F)F
b: O=C(NCc1cn(-c2ccccc2)nc1-c1ccccc1)c1ccc([N+](=O)[O-])cc1
c: CC(C)N1OC2CC1c1nc3ccccc3n1C2
d: COc1ccccc1OCc1nc(Cc2ccc(Cl)cc2)no1
Answer: a. O=C(/C(C=Nc1cccc(C(F)(F)F)c1)=C(/O)c1ccco1)C(F)(F)F
