Task: Answer the multiple choice question.
Query: Which drug has a 6.554\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) CCC(C)c1ccc(NC(=O)Nc2cnccn2)cc1
b.) COc1cccc(CN(C)CC(=O)Nc2sc3c(c2C#N)CCC3)c1OC
c.) Cl.NNC(N)=O
d.) CC1CCCCN1CCn1c(=S)[nH]c2ncccc2c1=O
Answer: c. Cl.NNC(N)=O
