Task: Answer the multiple choice question.
Question: Which drug has a 4.261\% 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. O=c1n(-c2ccccc2)c(=O)n2n1CC(O)C2
b. COc1cc(NC(=O)c2ccc(OC)c([N+](=O)[O-])c2)ccc1NC(=O)c1ccco1
c. CCOC(=O)Cn1nc(-c2ccc(F)cc2)oc1=O
Answer: b. COc1cc(NC(=O)c2ccc(OC)c([N+](=O)[O-])c2)ccc1NC(=O)c1ccco1
