Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 1.967\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COC(=O)C1=CN(C)C=C(C(=O)OC)C1c1ccc(O)c(OC)c1
b: CCOc1ccc(C(=O)OC2CCCN(C)C2)cc1.Cl
Answer: a. COC(=O)C1=CN(C)C=C(C(=O)OC)C1c1ccc(O)c(OC)c1
