Task: Answer the multiple-choice question.
Question: Which compound exhibits a 11.374\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C(Nc1nc2c(F)cc(F)cc2s1)c1ccc([N+](=O)[O-])o1
b. COc1ccc(N/C(N)=N/c2nc(C)cc(=O)[nH]2)cc1
Answer: b. COc1ccc(N/C(N)=N/c2nc(C)cc(=O)[nH]2)cc1
