Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.693\% 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) CC(=O)Nc1ccc(C(=O)OC2CCOC2=O)cc1
b) COc1ccc2[nH]c(=O)c(CN(CCN(C)C)C(=O)NCc3ccccc3)cc2c1
c) Nc1nnc(Cc2ccc(Cl)cc2)s1
d) O=C(OCCN1C(=O)c2ccccc2C1=O)c1cc2ccccc2o1
Answer: d. O=C(OCCN1C(=O)c2ccccc2C1=O)c1cc2ccccc2o1
