Task: Answer the multiple choice question.
Question: Which compound has a 4.843\% 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 other words.
Options:
a: CS(=O)(=O)N1CCC(C(=O)N2CCN(C(c3ccccc3)c3ccccc3)CC2)CC1
b: CN(C)c1ccc(C(=O)NCC(c2cccs2)N2CCOCC2)cc1[N+](=O)[O-]
Answer: a. CS(=O)(=O)N1CCC(C(=O)N2CCN(C(c3ccccc3)c3ccccc3)CC2)CC1
