Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 27.224% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CN(Cc1ccccc1Cl)C(=O)c1cnccc1C(F)(F)F
b Cc1ccccc1C(=O)Nc1ccnn1C1CCN(Cc2cnn(C(C)C)c2)CC1
c c1ccc(CSc2nnc(-c3ccccn3)n2-c2ccccc2)cc1
d O=c1oc(Cc2ccccc2)nc2ccccc12
Answer: d. O=c1oc(Cc2ccccc2)nc2ccccc12
