Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.003% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: C=CCn1c(Oc2ccccc2)nc2c1c(=O)n(C)c(=O)n2C
b: O=C(NN=C1CCCC1)c1ccc(Br)cc1
Answer: a. C=CCn1c(Oc2ccccc2)nc2c1c(=O)n(C)c(=O)n2C
