Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -2.237\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) CN1CC[C@]2(CCN3CCc4c(oc5ccccc45)[C@@H]3C2)N(C)C1=O.Cl
b) COc1ccc(CNC(=O)C2CCN(c3nnc(N4CCCC4=O)s3)CC2)cc1
Answer: a. CN1CC[C@]2(CCN3CCc4c(oc5ccccc45)[C@@H]3C2)N(C)C1=O.Cl
