Task: Answer the MCQ question.
Query: Which drug exhibits a 13.440\% 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 additional words.
Options:
a: COc1ccc(NS(=O)(=O)c2ccc(NC(C)=O)cc2)nn1
b: CCOC(=O)CSc1nc(C(C)(C)C)cc(C(F)(F)F)c1C#N
c: CCn1ncc([N+](=O)[O-])c1C(=O)Nc1nc2cccc(C)c2s1
