B Correct answer
Explanation

Succinylcholine is the only depolarizing neuromuscular blocker among the options. It works by mimicking acetylcholine and causing persistent depolarization of the motor endplate, leading to muscle paralysis. The other options (neostigmine, pancuronium, atracurium) are non-depolarizing agents or have different mechanisms.
