Task: Answer the multiple choice question.
Query: Which drug exhibits a 20.062\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] NS(=O)(=O)c1ccc2nc(NC(=O)c3ccc4c(c3)OCCO4)sc2c1
[b] NC(=O)Cn1cc(C(=O)c2ccccc2)c2ccccc21
[c] CN(C)c1cc(=O)n2c(n1)SCCC2
Answer: a. NS(=O)(=O)c1ccc2nc(NC(=O)c3ccc4c(c3)OCCO4)sc2c1
