Task: Answer the multiple choice question.
Query: Which compound exhibits a 3.020\% 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] O=C(NCCCN1CCCC1=O)c1cccc(NS(=O)(=O)c2ccc(Br)cc2)c1
[b] Cc1sc(NC(=O)c2ccco2)c(CN2CCC(C)CC2)c1C
Answer: a. O=C(NCCCN1CCCC1=O)c1cccc(NS(=O)(=O)c2ccc(Br)cc2)c1
