Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 18.865\% 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) CN(C)CCCOC(=O)c1ccc(Br)cc1
b) CCC1C(=O)CC(c2ccco2)NC1c1ccco1
c) COc1cc(C(=O)OCC(C)=O)c([N+](=O)[O-])cc1OC
d) CCCNC(=O)Cn1c(=O)oc2ccccc21
e) O=C(C1Cc2ccccc2O1)N1CCCCC1
Answer: c. COc1cc(C(=O)OCC(C)=O)c([N+](=O)[O-])cc1OC
