Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.337\% 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.) CCOC(=O)C1CCCN(C(=O)c2ccc([N+](=O)[O-])c(C)c2)C1
b.) COC(=O)C1=C(C)NC(=O)NC1/C=C/c1ccccc1
c.) O=C(OCCc1cc2ccccc2c(=O)o1)c1cccc(Br)c1
d.) COC(CN1C(=O)C(O)=C(C(C)=O)C1c1ccccn1)OC
e.) COc1ccc2cc(C#N)c(NC(C)C)nc2c1
Answer: d. COC(CN1C(=O)C(O)=C(C(C)=O)C1c1ccccn1)OC
