Which statement is correct concerning VFR operations in Class B airspace?

In Class B airspace, solo student pilots may operate under specific conditions set forth by the FAA, making the statement regarding solo student pilots correct. This includes having appropriate endorsements, being in communication with air traffic control (ATC), and complying with any restrictions that apply to their training. This provision allows student pilots to gain valuable experience in more complex airspace, provided they have the necessary training and permissions.

The other statements do not accurately reflect the regulations. A Private Pilot Certificate is not required for all flights in Class B; certain restrictions apply based on the pilot's certification and the aircraft being flown. Although the requirement for a transponder is true, it is not complete without mentioning that there are other operational requirements for flights in that airspace. Lastly, the assertion that a specific level of training is not required overlooks the necessity for student pilots to receive proper training and endorsements to operate in Class B airspace safely.
