Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.445\% 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) CCOC(=O)c1cc(NC(=O)COc2ccc([N+](=O)[O-])cc2)cc(C(=O)OCC)c1
b) CCOC(=O)c1c(NC(C)=O)sc2c(O)cccc12
c) CC(C)(C)c1cc(=O)n2c(C#N)c(C#N)nc2[nH]1
Answer: c. CC(C)(C)c1cc(=O)n2c(C#N)c(C#N)nc2[nH]1
