Problem statement: Answer the multiple choice question.
Query: Which compound has a 19.227\% 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 O=C1CCCC2=C1C(c1ccccc1)n1c(s/c(=C/c3cccc(F)c3)c1=O)=N2
b Cc1nc(-c2cccc(NS(=O)(=O)c3ccc4ccccc4c3)c2)cs1
c COCCN1CCn2c(nc3cc(NC(=O)c4ccc(OC)cc4)ccc32)C1
Answer: a. O=C1CCCC2=C1C(c1ccccc1)n1c(s/c(=C/c3cccc(F)c3)c1=O)=N2
