Answer:
A. Dialect
Step-by-step explanation:
Dialects are different forms of the same language characteristic for specific regions or social groups. For example, someone from the northern part of the USA might say hello, while someone from the South would say howdy.
Irregular subject-verb agreement (they was swimming instead of they were swimming) is a characteristic of some dialects.
The word yonder is archaic or belongs to a dialect. It means over there.
Diction is the choice and use of words and phrases in speech or writing. Every writer has their own diction.
The syntax is a set of rules words and phrases follow to create sentences in a language.
The tone in literature is what the author feels about a certain subject.
