Problem statement: Answer the multiple choice question.
Query: Which drug has a -0.290\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1cc2c(=O)n(CCC(=O)NCC3CCCO3)c(=O)n(CC(=O)Nc3ccc(C)c(C)c3)c2cc1OC
b: Cn1c(=O)c(=O)n(C)c2cc(S(=O)(=O)N3CCN(c4cccc(C(F)(F)F)c4)CC3)ccc21
c: COc1ccc(S(=O)(=O)NCCSC(C)(C)C)cc1
Answer: b. Cn1c(=O)c(=O)n(C)c2cc(S(=O)(=O)N3CCN(c4cccc(C(F)(F)F)c4)CC3)ccc21
