Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 9.465\% 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(O)/C=C/c1cn(-c2ccccc2)nc1-c1cc2ccccc2oc1=O
b: Cc1cc(C)nc(N(C#N)Cc2ccc([N+](=O)[O-])cc2)n1
Answer: a. O=C(O)/C=C/c1cn(-c2ccccc2)nc1-c1cc2ccccc2oc1=O
