Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.819\% 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.) CC(=O)c1c(N2CCN(C(=O)C3CCCO3)CC2)nc(=S)n(-c2ccccc2)c1C
b.) O=C(CSc1nc2cc(Cl)ccc2s1)NC(=O)NCc1ccco1
Answer: a. CC(=O)c1c(N2CCN(C(=O)C3CCCO3)CC2)nc(=S)n(-c2ccccc2)c1C
