Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 3.278% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. Cn1c(=O)n(CC(N)=O)c(=O)c2c1nc1n2CCCN1Cc1ccccc1
b. O=C(Cn1cnc([N+](=O)[O-])n1)N/N=C/c1cc(Cl)ccc1O
Answer: b. O=C(Cn1cnc([N+](=O)[O-])n1)N/N=C/c1cc(Cl)ccc1O
