Task: Answer the multiple-choice question.
Query: Which compound exhibits a 11.668\% human ether-à-go-go related gene (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=CCOc1cccc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2Cc2ccncc2)c1
[b] CC(C)CCN1CC(O)=C(c2nc3ccccc3[nH]2)C1=N
Answer: a. C=CCOc1cccc(C2C(C(=O)c3ccc(C)o3)=C(O)C(=O)N2Cc2ccncc2)c1
