Task: Answer the multiple choice question.
Query: Which compound exhibits a 18.979% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C1CCCC(O)=C1C1C2=C(CCCC2=O)OC2=C1C(=O)CCC2
b COc1ccc(N2CCN(C(=O)c3cccnc3)CC2)c([N+](=O)[O-])c1
Answer: a. O=C1CCCC(O)=C1C1C2=C(CCCC2=O)OC2=C1C(=O)CCC2
