What is the equipment carriage requirement for survival craft under GMDSS?

Correct Answer: Option D — All of these

GMDSS carriage requirements for survival craft are strictly defined by vessel type and size. These include specific quantities of two-way VHF radiotelephones and radar transponders (SARTs). These mandates ensure that survivors in lifeboats or liferafts have the necessary equipment to communicate and be located by responding search and rescue units.
