Task: Answer the multiple choice question.
Question: Which drug exhibits a -5.256% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) Cc1ccc(C)c(C2C(C#N)=C(N)Oc3cc(C)oc(=O)c32)c1
b.) CC(CNC(=O)c1cc(COc2ccc3ncccc3c2)on1)c1ccccc1
c.) O=C(CSc1ccccn1)Nc1nonc1[N+](=O)[O-]
d.) CC(=O)C1=C(C)NC(SCc2ccc(C#N)cc2)=C(C#N)C1c1ccco1
Answer: c. O=C(CSc1ccccn1)Nc1nonc1[N+](=O)[O-]
