Queen Elizabeth relies on logos by providing reasons why Parliament should not worry about the fact that she is unmarried and childless. (option C)
Logos is a persuasive technique in which the speaker appeals to logic and reasoning in order to convince the audience of something. This is the technique employed by Queen Elizabeth in the excerpt we are analyzing here.
The reasoning behind her words is that her not being married and not having children does not mean England's throne will be left without an heir. Besides that, she also argues that, if she did have a child, he or she might very well grow up to be someone unworthy of the throne.
With the information above in mind, we can select option C as the correct answer.
