What is the name of Beverly Crusher's son on the Enterprise-D?

Beverly Crusher’s son on the Enterprise-D is Wesley Crusher.

Wesley arrives aboard the Enterprise-D with his mother, Dr. Beverly Crusher, when she becomes the ship’s chief medical officer. Played by Wil Wheaton, he is introduced as an exceptionally intelligent teenager whose scientific and engineering abilities gradually earn Picard’s trust.

Wesley’s father, Jack Crusher, died on a mission while serving under Jean-Luc Picard’s command aboard the USS Stargazer. That history creates early tension between Wesley and Picard, but Picard eventually becomes an important mentor and grants Wesley increasing responsibility, including an acting ensign position.

Wesley later enters Starfleet Academy and joins Nova Squadron. His role in concealing the circumstances of a cadet’s death becomes central to “The First Duty,” one of his most significant TNG stories. The other options are also Star Trek characters, but Tom Paris, Alexander Rozhenko, and Jake Sisko are not Beverly Crusher’s son.
