What does the acronym SCUBA stand for?

Self-Contained Underwater Breathing Apparatus
Submersible Compressed Underwater Breathing Apparatus
Senior Class Underwater Breathing Association
Submerged Compressed Underwater Breathing Apparatus

The correct answer is: Self-Contained Underwater Breathing Apparatus

The acronym SCUBA stands for Self-Contained Underwater Breathing Apparatus. This term accurately describes the equipment used for diving, which allows divers to breathe underwater without reliance on surface-supplied air. The 'self-contained' aspect indicates that the air supply is carried by the diver in tanks, making it possible for them to operate independently in underwater environments. The other options propose variations that do not reflect the widely accepted and recognized definition. For example, while 'Submersible' and 'Compressed' might suggest an underwater context, they do not convey the fundamental meaning intended in the traditional SCUBA acronym. Additionally, 'Senior Class Underwater Breathing Association' is unrelated to diving equipment altogether, and 'Submerged Compressed Underwater Breathing Apparatus' introduces unnecessary complexity without aligning with the established terminology. The correct answer succinctly captures the essence of the apparatus that has become synonymous with recreational diving.
