Which of the following sentences is correctly punctuated, including only necessary commas?

A. The map, that we requested turned out to be incorrect.

C. The season of drought, worried the farmers,

B. Maria turned off the lights, and locked the door

D. The agreement included, she noticed, training for part-time staff

I believe the answer is D.

Explanation:

The sentence is "The agreement included, she noticed, a training for part time staff." Normally, the sentence would be "The agreement included training for part-time staff", however, "she noticed" is added, which requires commas to make sense.

The other sentences include commas that are out of place and unnecessary.

A. should be "The map that we requested turned out to be incorrect"

B. Should be "Maria turned off the lights and locked the door

C. Should be "The season of drought worried the farmers."

D. Is correct.
