Task: Answer the MCQ question.
Question: Which drug exhibits a -1.823% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cc1cc(N)ccc1N1CCCC1.Cl
b: O=C(CCCOc1ccc(Cl)cc1Cl)Nc1ccccn1
