Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.964\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) COc1ccc(CNC(=O)C2(CC3CC(c4ccccc4)=NO3)CCN(C(=O)Cc3ccc(F)cc3)CC2)cc1
(b) CC1CCN(C(=O)COC(=O)[C@H](C)NS(=O)(=O)/C=C/c2ccccc2)CC1
Answer: b. CC1CCN(C(=O)COC(=O)[C@H](C)NS(=O)(=O)/C=C/c2ccccc2)CC1
