Explanation:

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

• Option A and D describe slang (informal language restricted to a group/context), not a language branch.
• Option C describes language (spoken/written/signed communication and pronunciation variations), not a branch.
• Option B defines a language branch as a collection of languages related by a common ancestor before recorded history, which matches the term's definition.

Answer:

B. A collection of languages related to each other through a common ancestor long before recorded history.
