Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.971\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COc1ccc(NC(=O)c2c3c(nc4ccccc24)CCN(Cc2ccccc2)C3)c(OC)c1
b: CSCC[C@H](NS(=O)(=O)c1ccc(C(C)=O)cc1)c1nnc2ccccn12
Answer: b. CSCC[C@H](NS(=O)(=O)c1ccc(C(C)=O)cc1)c1nnc2ccccn12
