Doğru Cevap: Zorunlu Değildir ( Hiçbiri )

Açıklama: "250 GRT luk bir gemide bulunması gereken SART ve VHF El Telsizi Sayısı Zorunlu Değildir ( Hiçbiri ) çünkü geminin boyutu ve sınıfına göre farklı bir ekipman listesi gerektirir." (Note: GRT stands for Gross Register Tonnage, which is a measure of a ship''s size. The International Convention for the Safety of Life at Sea (SOLAS) requires certain safety equipment on board ships, but the specific requirements vary depending on the ship''s size, type, and class. In this case, the question is asking about the number of SART (Search and Rescue Transponder) and VHF (Very High Frequency) radio sets required on a 250 GRT ship, and the correct answer is "None" because the specific requirements depend on the ship''s characteristics.)
