Among the options, the one that is correctly punctuated is:
D. Dee passed her math test with a perfect score: she studied all week long.
To answer the question, we must understand how to use a colon.
A colon can be used to connect independent sentences. Usually, the second sentence presents information or an explanation that adds to the meaning of the first one.
It is not possible to use a colon twice in the same sentence. As a matter of fact, two colons might be a lot even if in different places of the same paragraph.
Adding information after the colon that is non-related to the information in the first sentence is also wrong.
With that in mind, we can choose option D as the best one. It only uses colon once, and the information after it adds to the meaning of the sentence.
