I will go through the options:

a. The Mesoamericans are attributed with creating a technique that used the painters fingers and yucca fiber brushes to apply reddish pigment made from iron oxide.

Now, I have read a lot about Mesoamerica but I have never heard about this. this is a good candidate for the correct answer, but let's look at the others too:

b. The different civilizations were linked by cultural similarities and trade.

This is definitely true! The trade was visible for example in food from other places being found (for example sea food being found in archeological founds in Mexico city)

c. Mesoamerica includes the land between the continents of North America and South America. Its landforms range from rainforests to semiarid mountains.

This is true - it's just the description of its geography

d. There was a sharp division in Mesoamerican civilizations among the elite and commoner classes.

This is also true - the rich were super rich and the poor were often sacrificed.

So since b, c, d are true, we choose A) as the not-true answer!
