Answer:
D. All of these.
Explanation:
During the research for information on a required topic or literary project, texts, descriptions, citations or graphic data are used to build up the scholarly work. When this source is mentioned, it is known as a reference and is used to validate the literary work produced.
There are three types of sources:
1. Primary source.
2. Secondary source.
3. Tertiary source.
Primary sources of information are original and first hand documentation of a work that has not been interpreted. For example:
• Works of fiction
• Diaries
• Interviews
• official documents, such as census data and legal texts
• Objects, such as archaeological findings
• Numeric data
• Corpora
Secondary sources of information are analysis, comments or interpretations of an original documentation. For example:
• Research articles
• Biographies
• Monographs
Tertiary sources are information obtained from other sources that have been summarized or complied. Since they are compiled from primary and secondary sources and depending on the level of academic work required, it is recommended that a primary or secondary source be used to validate the information presented.
These include:
• Textbooks
• Study guides
• Encyclopedias and wikis
• Indexes and other classification systems
