(B) Lewis H. Latimer

Explanation:

Lewis H. Latimer was citizen of Massachusetts. Alongside Woods, Latimer was one of the primary significant African American designers. He initially filled in as a right hand to Alexander Graham Bell.

Some have guaranteed that Latimer, not Bell, but invented the telephone. However, this is impossible since Latimer regularly defended Bell's cases to first creations in court.

Latimer made his most significant logical commitments here by improving the light that was invented by Edison.
