Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -17.838\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a NC(=O)c1cc(-c2cccnc2)nc2ccc(Br)cc12
