Answer:
Persuade her audience that she will never make personal decisions that will harm England.
Step-by-step explanation:
Queen Elizabeth's speech from her "Response to Parliament’s Request That She Marry" was given from the occasion that arose where the parliament expected her to marry so that a legitimate heir to the throne may come. The Queen's response was her way of assuring them that the throne's future need not rely merely on the availability of a legitimate heir from her own.
In the given excerpt, Queen Elizabeth assures that the "realm shall not remain destitute of any heir". She also stated that "the weal, good, and safety whereof, I will never shun to spend my life; and whomsoever it shall be my chance to light upon, I trust he shall be such, as shall be as careful for the realm as you". This was done in an attempt to persuade her audience that she will not take any personal decisions that will come on the way of England.
Thus, the correct answer is the third option.
