Problem statement: Answer the multiple choice question.
Query: Which drug has a 3.137\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. COc1cc(C(=O)Nc2cccc(-c3nc4ncccc4o3)c2C)cc(OC)c1OC
b. O=C(/C=C/NNC(=O)c1ccccc1)c1ccc([N+](=O)[O-])cc1
c. O=C(COc1ccccc1)Nc1ccc(Cl)cn1
d. O=[N+]([O-])c1ccccc1CNC(Cc1ccccc1)c1ccccc1
e. Cc1c(NC(=S)N2CCN(c3cccc(Cl)c3)CC2)c(=O)n(-c2ccccc2)n1C
Answer: c. O=C(COc1ccccc1)Nc1ccc(Cl)cn1
