Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 9.945\% 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 COc1ccc(/C=C2\N=C3CCCCCN3C2=O)cc1
b COC(=O)c1sc2nc(CN3CCN(c4cccc(C(F)(F)F)c4)CC3)[nH]c(=O)c2c1C
c COc1ccccc1NS(=O)(=O)c1ccc2c(c1)n(C)c(=O)n2C
Answer: b. COC(=O)c1sc2nc(CN3CCN(c4cccc(C(F)(F)F)c4)CC3)[nH]c(=O)c2c1C
