C.

D.
Maya found out that her Uncle went to college in Nebraska. She had never known that about uncle mike before.

Answer 1

The correct capitalization is in option B:
"Maya found out that her uncle went to college in Nebraska. She had never known that about Uncle Mike before."

In this sentence, "Uncle" is capitalized because it is used as a proper noun (a title before a name), while "uncle" in the first part of the sentence is not capitalized because it is used as a common noun.
