Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.642\% 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. COc1ccc(CCNC(=O)CC(=O)N/N=C/c2ccc(Br)cc2)cc1OC
b. COC(/C=C/Nc1ccc(OC)cc1)=C(C#N)C#N
Answer: a. COc1ccc(CCNC(=O)CC(=O)N/N=C/c2ccc(Br)cc2)cc1OC
