Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.678\% 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, b, or c without using any additional words.
Options:
(a) COc1ccc(NS(=O)(=O)c2ccc(N3CCCCC3)c(N)c2)cc1
(b) CCOc1nc2cnccc2n(CC(=O)Nc2cccc(C)c2)c1=O
(c) CC(=O)CC[C@@H](C)O[C@@H]1OC(C)[C@H](O)CC1O
Answer: a. COc1ccc(NS(=O)(=O)c2ccc(N3CCCCC3)c(N)c2)cc1
