Task: Answer the multiple-choice question.
Query: Which compound has a 18.862\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. C=C(C)C1CC=C(C)/C(=N/NC(=O)COc2cccc3ccccc23)C1
b. COCCN1C(=O)NC(=O)/C(=C\c2ccc(F)cc2)C1=O
c. CCCSc1ccc([C@@H]2[C@H]3C(=O)N(CC)C(=O)[C@H]3[C@]3(C(=O)OC)CCCN23)cc1OC.O=C(O)C(F)(F)F
Answer: b. COCCN1C(=O)NC(=O)/C(=C\c2ccc(F)cc2)C1=O
