Task: Answer the multiple-choice question.
Question: Which compound exhibits a 14.764\% 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 additional words.
Options:
a) O=C(O)c1ccc(COc2ccccc2Cl)cc1
b) O=C(OCC(=O)N1N=C(c2ccc(Cl)cc2)CC1c1ccco1)c1ccccc1O
c) Cc1cccc2cc(COC(=O)COc3ccccc3)c(=O)[nH]c12
d) COc1cc(NC(=O)c2cccs2)ccc1NC(=O)c1ccccc1Cl
Answer: a. O=C(O)c1ccc(COc2ccccc2Cl)cc1
