Task: Answer the multiple choice question.
Query: Which compound exhibits a 15.971\% 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, or c without using any other words.
Options:
a. COc1ccc(OC)c(NC(=O)c2ccc(CSc3ncccn3)cc2)c1
