Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -18.692% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COc1ccc(-c2c(NCCc3ccccc3)c(=O)c2=O)cc1
b: CCO[C@@H]1OC(C(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)=C[C@H](C2CC2)[C@H]1CCCO
Answer: b. CCO[C@@H]1OC(C(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)=C[C@H](C2CC2)[C@H]1CCCO
