Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.304\% 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) C=CCOc1ccc2cccc(/C=N/NC(=O)c3cc4cc([N+](=O)[O-])ccc4s3)c2c1
(b) COC(=O)c1c(NC(=O)/C=C/C(=O)O)sc(C)c1-c1ccc(C)c(C)c1
Answer: a. C=CCOc1ccc2cccc(/C=N/NC(=O)c3cc4cc([N+](=O)[O-])ccc4s3)c2c1
