This question is missing the sentence. I was able to find it online. It is the following:

Their math teacher informed them that division problems would not be on the test. The class was not happy to hear that these kinds of problems would be excluded.

The meaning of "excluded" as it is used in the sentence above is:

A. kept out

Explanation:

A context clue is a piece of information an author gives to help readers understand the meaning of a word that may be regarded as difficult or unusual. In the sentences we are analyzing here, the context clue for the meaning of "excluded" is given before the word itself appears. When the author says, "division problems would not be on the test," he is offering the clue. Some problems will be kept out, excluded, or simply not included in the test.
