The correct answer is A.
The opening of section 2 from "An Occurrence at Owl Creek Bridge introduces the character of Peyton Farquhar.
It explains the reader that Farquhar was a planter and politician from a respected Alabama family. He was a slave owner, a secessionist and a friend to the Southern cause.

Answer:
The best option to modify this sentence is: change then to than.
Explanation:
There is no mistake in the way the sentence is punctuated. Also, "calm" is an adjective referring to lake, so it does not need to be changed. "Calmly" is an adverb, and would be used differently.
However, there is a misspelling in "then". The correct word is "than", which a part of the expression "would rather... than...", which expresses preference. That is the only problem with the sentence. The correct form is:
If I were a duck, I would rather swim in a calm lake than a fast moving stream.
Another example with "would rather... than..." would be:
She said she would much rather not buy it at all than borrow the money to do it.
The second one and last one i think maybe not the second one but for sure the last one
