Task: Answer the multiple choice question.
Question: Which compound has a -1.865\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. COc1ccc(C(=O)NNC(=O)CN2CCC(n3nnc4cc(F)ccc43)CC2)cc1
b. COc1ccc(C2C(C#N)=C(N)OC3=C2C(=O)CCC3)cc1Cn1nc(C)c([N+](=O)[O-])c1C
Answer: b. COc1ccc(C2C(C#N)=C(N)OC3=C2C(=O)CCC3)cc1Cn1nc(C)c([N+](=O)[O-])c1C
