Task: Answer the multiple choice question.
Query: Which drug has a -6.944\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) CCCn1c(=O)c(Br)cn(-c2ccccc2C)c1=O
b) CCOC(=O)c1[nH]c(=O)[nH]c1CSc1nc(C)cc(C)n1
c) COc1ccc(CN(C)CC(=O)Nc2cc(OC)c([N+](=O)[O-])cc2C)c(OC)c1
Answer: c. COc1ccc(CN(C)CC(=O)Nc2cc(OC)c([N+](=O)[O-])cc2C)c(OC)c1
