In " you, m'am," which line is an example of dialect?
a.
"maybe you ain't been to your supper either, late as it be."
b.
"then, roger, go to that sink and wash your face."
c.
"well, i wasn't going to say that."
d.
"there's nobody home at my house."

The example of dialect is

A. "Maybe you ain't been to your supper either, late as it be."

The word ain't and the phrase, late as it be. Is not proper but a dialect is a variety of a language that uses different pronunciation, grammar or vocabulary. Each culture has their own dialect.

Hope this helps.
