Task: Answer the multiple-choice question.
Query: Which drug has a 4.002\% 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 CCOC(=O)c1cc([N+](=O)[O-])c([N+](=O)[O-])cc1NC(C)=O
b O=C(CCC1CCCCC1)Nc1nccs1
c COc1cc2c(cc1OC)CN(C(=O)c1cc(=O)c3ccccc3o1)CC2
d CN(C)c1ccc(CN2CCCCCC2)cc1
Answer: c. COc1cc2c(cc1OC)CN(C(=O)c1cc(=O)c3ccccc3o1)CC2
