Task: Answer the MCQ question.
Question: Which drug exhibits a 16.731\% 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.) Cc1cc(C#N)c(C)c(SCc2[nH]nc3c2C(c2ccccc2)C(C#N)=C(N)O3)n1
b.) CCOC(=O)C1CCCN(c2c(C(=O)c3ccccc3)cnc3ccc(OC)cc23)C1
c.) Cc1ccccc1NC(=O)Nc1ccccc1C(N)=O
