If your question is about Queen Elizabeth's purpose in this excerpt, the correct answer is C. to persuade her audience that she will not make any personal choices that harm England.

Explanation:

The Parliament bid the queen to marry and produce an heir not just because it was a social convention at the time, but because they believed it was in the best interest of England and all English people. In this speech, the queen turns this argument on its head, saying that she indeed intends to act in England's best interest, and that her marriage or lack thereof won't affect the state politics in any way. Her personal choice, therefore, has nothing to do with her high office.

If you are looking for the common purpose of this and the excerpt from Queen Elizabeth's Address to the Troops at Tilbury, then the answer is B. I am come amongst you, as you see, at this time, not for my recreation and disport, but being resolved in the midst and heat of the battle, to live or die among you all. This excerpt shows that she is willing to sacrifice her own life if need be. She explicitly says that she hasn't come for "recreation and disport" - therefore, for entertainment or putting on a show.
