b our spoken, written, or signed words and the ways we combine them to communicate meaning the manner in which people speak and the way words are pronounced in different parts of the world
c a language that is written as well as spoken
d the language adopted for use by the government for the conduct of business and publication of documents. a collection of languages related to each other through a common ancestor long before recorded history.

Explanation:

To determine the correct definition of "Official Language", we analyze each option:

• Option A describes a lingua franca (a common trade language for different native speakers).
• Option B defines "language" in general (spoken/written communication and pronunciation variations).
• Option C is too vague and does not capture the "official" (government - designated) aspect.
• Option D: The first part ("The language adopted for use by the government for the conduct of business and publication of documents") matches the definition of an official language. The second part (about a language family) is extraneous but the first part is correct.

Answer:

D. The language adopted for use by the government for the conduct of business and publication of documents. A collection of languages related to each other through a common ancestor long before recorded history.
