The correct answer is B. To entertain

Explanation:

In general terms, texts can have four main purposes to persuade, to inform, to describe or to entertain. In the case of entertaining this includes texts written mainly with the objective of amusing the audience, this occurs when telling a story, because most stories do not aim at convincing the audience about an idea or teaching the audience about some topic but aim at catching the attention of the readers and keeping them occupied for some time.

This is the purpose of the text presented, because the author of this text is only telling a story and he or she includes elements such as "Brianna always looked forward to the winter season in Colorado" or "she couldn't wait to show off her skills" that catch the attention and amuse the reader.

the present continuous is a verb tense which is mainly used to indicates that an action is in progress at the moment of speaking.  

it is formed using: person + verb to be (am/is/are) +verb + - ing form

in addition, the present continuous is also used in order to express things that will or will not happen in the near future.

example: i am having dinner with some friends tonight.

the speaker sometimes   uses it   to express that an action is repeated and it causes irritation on the part of the speaker

example: my sister is constantly complaining about everything.
