Problem statement: Answer the multiple choice question.
Query: Which drug has a 7.955\% 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) C=CCN1C(=O)C(CCCC)NC1=S
b) Nc1nc(-c2ccc(Cl)cc2)nc(-c2ccc(Cl)cc2)n1
Answer: a. C=CCN1C(=O)C(CCCC)NC1=S
