Task: Answer the multiple choice question.
Query: Which compound exhibits a 13.992\% 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 COc1ccc(OC)c(CN2CCN(C(=O)[C@@H](NC(=O)c3cccc(C)c3)C(C)C)CC2)c1
b COc1cccc(-n2c([S-])c(C(=O)Nc3ccc(C(F)(F)F)cc3)[n+]3ccccc23)c1
c O=C(NCc1ccccc1)c1ccc2nc(N3CCOCC3)sc2c1
d O=C(N/N=C1/CCc2ccccc21)C1CC1
Answer: b. COc1cccc(-n2c([S-])c(C(=O)Nc3ccc(C(F)(F)F)cc3)[n+]3ccccc23)c1
