Problem statement: Answer the multiple choice question.
Query: Which drug has a 19.976\% 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(CNC(=O)Cc1ccccc1)N=Nc1c(O)[nH]c2ccc(Br)cc12
b) CCC(C)[C@H](NS(=O)(=O)c1ccc(C)cc1)C(=O)N1CCC(C(=O)N2CCC(C(=O)OC)CC2)CC1
Answer: a. O=C(CNC(=O)Cc1ccccc1)N=Nc1c(O)[nH]c2ccc(Br)cc12
