Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 19.607% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) O=C(CCC(=O)NNC(=O)COc1ccc(Br)cc1)NCc1ccccc1
b.) O=C(Nc1ccccc1C(=O)N1CCCCC1)c1cc(F)c(F)cc1Cl
Answer: a. O=C(CCC(=O)NNC(=O)COc1ccc(Br)cc1)NCc1ccccc1
