Task: Answer the multiple choice question.
Query: Which compound has a 6.841\% 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(/C=C/c1ccccc1)NCCS(=O)(=O)N1CCN(c2ccccc2)CC1
[b] Cc1cc(NC(=O)Cn2cnc3c(nnn3-c3cccc(F)c3)c2=O)no1
Answer: a. O=C(/C=C/c1ccccc1)NCCS(=O)(=O)N1CCN(c2ccccc2)CC1
