Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 9.644\% 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 other words.
Options:
a: CCOC(=O)c1c(NC(=O)CCCC(=O)O)sc2c1CCC2
b: Cc1c(Cl)cccc1N1C(=O)CC(N(O)c2ccccc2)C1=O
c: COc1ccc(CNc2nnnn2C)c(OC)c1
d: Cn1c(=O)c([N+](=O)[O-])c(NCc2ccccc2)c2ccccc21
Answer: c. COc1ccc(CNc2nnnn2C)c(OC)c1
