Task: Answer the multiple choice question.
Query: Which drug exhibits a 11.275\% 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 COc1ccnc(Nc2ccc(C)c(C)c2)c1C#N
b CC1(C)C(=O)OC(C(=O)c2ccc(Cl)cc2)C(C)(C)C1=O
c COC(=O)c1cc(OC)c(OC)cc1NC(=S)Nc1cc(Cl)ccc1OC
d COC(=O)c1ccc(OC(=O)N2CCOCC2)cc1
Answer: d. COC(=O)c1ccc(OC(=O)N2CCOCC2)cc1
