Task: Answer the MCQ question.
Query: Which drug has a 2.526\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: NS(=O)(=O)c1ccc(CNS(=O)(=O)c2ccc3ccccc3c2)cc1
b: CCN(C(=O)CSc1nc2ccc(OC)cc2[nH]1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
c: CNS(=O)(=O)c1ccc(NS(=O)(=O)c2ccccc2F)cc1
d: COc1ccc(CNC(=O)Cn2ncn3cccc3c2=O)cc1
Answer: a. NS(=O)(=O)c1ccc(CNS(=O)(=O)c2ccc3ccccc3c2)cc1
