Answer:
It is a paragraph.
Explanation:
In writing, especially in prose, a paragraph is a group of sentences arranged in a sequence that develops a certain topic. Paragraphs begin with a new line and, often, an indentation. Each paragraph discusses a different topic, and their length may vary according to that topic or to the type of material being written. Paragraphs usually have a main statement that is further developed by support sentences. The paragraphs themselves are used to develop the main idea of the text.
