Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.639% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a) COC(=O)Nc1nnc(-c2ccccc2OC)s1
b) O=C(C1=COCCO1)N1CCN(C(c2ccccc2)c2ccccc2)CC1
Answer: a. COC(=O)Nc1nnc(-c2ccccc2OC)s1
