Task: Answer the multiple-choice question.
Query: Which drug exhibits a 14.815\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=[N+]([O-])c1ncccc1OCc1ccc(Br)cc1F
b. COc1ccc(C(=O)/C=C(\N)C(F)(F)F)c(O)c1
c. Cn1c(=O)c2c(-c3ccc(C(C)(C)C)cc3)n(N3CCOCC3)cc2n(C)c1=O
Answer: a. O=[N+]([O-])c1ncccc1OCc1ccc(Br)cc1F
