Task: Answer the multiple choice question.
Query: Which drug has a 4.348\% 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. COc1ccc(N2CCN(C(=O)CN3CCN(C(c4ccccc4)c4ccccc4)CC3)CC2)cc1.Cl
