Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.394\% 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) COc1cc(N/C=C(\C(C)=O)c2ccccc2)cc(OC)c1
(b) COc1ccc(NC(=O)COc2nc3ccccc3nc2N2CCOCC2)c(OC)c1
Answer: a. COc1cc(N/C=C(\C(C)=O)c2ccccc2)cc(OC)c1
