With the family and the friends and people with whom we have intimacy we use a more relaxed language, that is, an informal language. With hierarchical superiors, or with a large crowd where we do not have intimacy with people we use a more careful language, that is, a formal language. Thus, we can conclude that in "The Swan", the feeling that the speaker is addressing a large audience creates a formal tone.
Formal language can also be named as formal registration. It is used when there is no familiarity between the communication interlocutors or in situations that require more seriousness.
The tone is demonstrated as the approach or attitude of the author towards a particular subject matter which is reflected through the writing style or usage of words in the poem. It determines how the audience would perceive or respond to a literary work. It helps to evoke the desired response from them by proposing the perspective through which the audience would consider the text.
As per the question, if the speaker is addressing a large audience then he/she must employ a formal tone as this would not only reflect the author's attitude and knowledge about the subject but also help establish his/her credibility before the audience. Thus, <u>option A</u> is the correct answer.
