Whenever we talk about the "degree" of something, we are talking about how much of it there is. Thus, the "degree of anger" that someone is feeling is the amount of anger that he or she is feeling in a particular situation. Thus, "degree" can mean "how far," "amount," or "extent." The word "extent" is a synonym for "area" (or "distance") but it also is a good synonym for "degree." Think of some expressions you might use. You could say, "To what degree was the building damaged in the earthquake?" You could, however, also say, "What was the extent of the damage to the building during the earthquake?"

Based on the options for this question, it is clear that the word "ridicule" is being used as a noun. All of the options are nouns. Now, the verb form of "ridicule" means to make fun of or to mock. Thus, the noun "ridicule" describes the kind of mockery that happens whenever someone is made fun of. While this kind of mockery is a kind of abuse, the general idea of ridicule has to do with mocking and "laughing at" someone else. Hence, the best option is "mockery."

Do not confuse the word "hospitality" with "hostility." The latter means enmity—quite different from "hospitality"! "Hospitality" is the kind of kindness or help that we show to others such as neighbors or guests. Hence, the best option is "kindness," which expresses this idea of helping others.

Whenever something is "profound," it is very deep and intensely influential. A "profound" feeling is a very deep feeling. The word "profundity" is a noun that describes something that has such a depth. For example, whenever someone says something that is very insightful and true, we say that he or she has expressed something of great profundity. This is the sense implied by the word in this question. Hence, you can say that he or she expressed something of "great depth"—speaking metaphorically, of course!
