Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -3.949% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] NC1=NC[C@H](Cc2ccccc2)N1CCc1cc(C(F)(F)F)cc(C(F)(F)F)c1
[b] CCCCCCCCN1[C@@H](CC(C)=O)c2cc(C(F)(F)F)ccc2S1(=O)=O
Answer: b. CCCCCCCCN1[C@@H](CC(C)=O)c2cc(C(F)(F)F)ccc2S1(=O)=O
