Here, we take a look at the solutions provided with the view to choosing the best fit.
In Option A - INCORRECT. This is an express statement that shows the mind of the writer. Unfortunately, it doesn't answer the question raised here. Yo can't answer a question with the question itself.
In Option B - INCORRECT. Here, a different meaning was envisaged. It seeks to express that Dinosaurs ''stood'' in a particular position that's different from the way it is used to on this occasion.
Option C - INCORRECT. This is just too much of grammar and unnecessary semantics. It could have been simpler yet still retaining the meaning.
In Option D - CORRECT. This is a much simpler statement that expresses the mind of the writer even to a layman. It is the most correct of all the options. I guess you like Dinosaurs too.
Option E - INCORRECT. This is all neither case of unnecessary verbosity in language. Too much emphasis on the words used without adding different meaning or orientation.
