Which one of the following statements about a Gate Turn-Off (GTO) thyristor is NOT true?

• A. The GTO retains the basic 4 layer structure (PNPN) of a conventional thyristor
• B. The I-V characteristics of the GTO in the forward direction is different as compared to a conventional thyristor
• C. Due to its special structure, the GTO has limited reverse blocking capability as compared to a conventional thyristor
• D. The GTO has gate controlled turn-off capability unlike a conventional thyristor
