Answer:
A.
Step-by-step explanation:
Transition can be defined as an action of going from one state of course to the another. It is used to hint the change that's going to take place in a paragraph, line, or sentence. These transitions can be signalled by using punctuation marks.
The analogy that best describes the transition in a paragraph is the link in a chain. A transition works like a link in a chain. It helps in binding and moving from one state of action to the another smoothly without any interruption.
So, the correct answer is option A.
