Task: Answer the multiple-choice question.
Question: Which drug exhibits a 13.587\% 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 CCCOc1ccc(-c2nnc(-c3cccs3)o2)cc1
b CCCc1[nH]n(-c2ccc([N+](=O)[O-])cc2)c(=O)c1C(C)=NCc1ccncc1
c Nn1cnc2scc(-c3cccs3)c2c1=O
Answer: a. CCCOc1ccc(-c2nnc(-c3cccs3)o2)cc1
