Question

Which sentence is punctuated correctly?

A.
"Boy," Darren replied, "You weren't kidding."

B.
Fred asked, "do you have an extra pencil, Adam?"

C.
"I visit my grandmother at the nursing home," said Juanita, "at least once a week."

D.
"where have you been?" Ronald asked.

Answer 1

A. is punctuated correctly because it is the only sentence that uses correct capitalization. B does not capitalize after the "d" in "do," C does not capitalize the "a" in "at" and D does not capitalize the "w" in "where." 

Answer 2

Honestly, I know that it is either A. or D. I would most likely go with D.
