Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.906\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CC1CC(C(F)(F)C(F)(F)F)n2nc(C(=O)O)cc2N1
b: CCN(CC)CCNC(=O)CS(=O)Cc1nc(-c2ccc(Cl)cc2)oc1C
Answer: a. CC1CC(C(F)(F)C(F)(F)F)n2nc(C(=O)O)cc2N1
