Problem statement: Answer the multiple choice question.
Query: Which compound has a 5.098\% 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 additional words.
Options:
a. COc1cccc(/C=C2/CN(C)CC3=C2OC(N)=C(C#N)C3c2cccc(OC)c2)c1
b. O=C(CN1C(=O)C2CC=CCC2C1=O)OCc1cc(=O)n2cc(Br)ccc2n1
Answer: a. COc1cccc(/C=C2/CN(C)CC3=C2OC(N)=C(C#N)C3c2cccc(OC)c2)c1
