Task: Answer the multiple choice question.
Query: Which compound exhibits a -6.156% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a COc1ccccc1CNC(=O)c1sccc1-c1ccccc1
b O=[N+]([O-])c1nn(-c2ccccc2)n(O)c1=NCc1ccc2c(c1)OCO2
c NC(=O)C1CCN(C(=O)CCNS(=O)(=O)c2cc(Br)cnc2N)CC1
Answer: a. COc1ccccc1CNC(=O)c1sccc1-c1ccccc1
