Problem statement: Answer the multiple choice question.
Question: Which drug has a 18.733\% 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 other words.
Options:
a: COc1cc(N)c(Cl)cc1C(=O)OCC(=O)c1cccs1
b: COc1ccc(-c2csc(NC(C)c3nc4cc(Cl)c(Cl)cc4n3CCCO)n2)cc1
c: CCOc1ccc(CC(C(N)=O)C(N)=O)cc1
d: CCNC(=O)C(C)Oc1ccc(Cl)cc1Cl
e: NC(=O)NOCc1c(F)cccc1Cl
Answer: a. COc1cc(N)c(Cl)cc1C(=O)OCC(=O)c1cccs1
