Task: Answer the multiple-choice question.
Query: Which drug exhibits a 15.215\% 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, b, c, d, or e without using any other words.
Options:
a: O=C(CCCc1ccccc1)NCc1ccccn1
