The part of an informational text that supports a central idea is A - evidence. Evidence refers to the facts, data, examples, or expert opinions provided in the text to substantiate or support the central idea being conveyed. It helps to strengthen the argument or point being made and convince the reader of the validity or credibility of the central idea.

The part of an informational text that supports a central idea is typically the evidence. To determine the answer to this question, we need to understand the purpose and structure of an informational text.

An informational text is written to convey information and typically presents facts, ideas, or arguments on a particular topic. The central idea of an informational text represents the main point or thesis that the author is trying to convey. Supporting this central idea requires the use of evidence, which is factual information or examples that provide proof or support for the author's claims or arguments.

Transitions, on the other hand, are words or phrases that bridge ideas and help to create a coherent flow within the text, but they do not directly support the central idea. Citations of sources are used to provide credibility and give credit to the original authors or researchers whose work is referenced in the informational text. While citing sources is important for academic integrity, it does not inherently support the central idea. Similarly, dialogue can provide additional context or perspectives, but it may not directly contribute to supporting the central idea unless the dialogue contains evidence or points that align with the main argument.

Therefore, the correct answer is A - evidence. Evidence is the part of an informational text that supports and validates the central idea by providing factual information, examples, statistics, or expert opinions.
