Concept:A limerick is a short, humorous poem that is made up of exactly five lines and a strict rhyme pattern.
Explanation:In a limerick, the first, second, and fifth lines are long and rhyme with one another.
The third and fourth lines are short and rhyme with each other.
This produces the conventional rhyme scheme
AABBA.
The poem is meant to be witty and amusing, so humour is one of its chief qualities.
Its length is always fixed at five lines.
Options A and B are incorrect, since a limerick is neither ornate and formal nor made up of seven lines.
Option D is incorrect because it does not require a "stinging" climax.
Therefore, the best choice is the option that states humour, rhyme scheme, and five lines together.
Answer:Option C: humour, rhyme scheme and five lines.
