Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 18.753\% 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=c1[nH]c(=O)n(-c2ccccc2F)c(O)c1C=NCCC1=CCCCC1
(b) Cc1cc(C(=O)N(C)C)sc1-c1ccccc1
(c) CC(=O)Nc1ccc(NS(=O)(=O)c2cn(C)c(=O)n(C)c2=O)cc1
Answer: a. O=c1[nH]c(=O)n(-c2ccccc2F)c(O)c1C=NCCC1=CCCCC1
