Task: Answer the multiple choice question.
Question: Which compound exhibits a -5.333\% 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) CC1(C)Oc2ccc(C(=O)N3CCOCC3)cc2N(CC(=O)N2CCOCC2)C1=O
(b) Cc1ccc(NS(=O)(=O)c2cc(C(=O)N3CCN(C)CC3)ccc2C)cc1
Answer: b. Cc1ccc(NS(=O)(=O)c2cc(C(=O)N3CCN(C)CC3)ccc2C)cc1
