Answer:
D. keywords
Step-by-step explanation:
It is conventional to capitalize keywords when writing pseudocode. Keywords are predefined words that have specific meaning in the programming language. They are used to perform specific tasks and have predefined meaning, it is important to distinguish these words from other words in the pseudocode. Capitalizing keywords makes it easier to read and understand the pseudocode, and can help to prevent errors in coding.
