127. On the gas turbine shown in the illustration, which of the following best describes the main principle of operation of the component contained within the area labeled «C»

The combustor section (labeled 'C') operates on the Brayton cycle, characterized by continuous combustion and heat addition at nearly constant pressure. This process distinguishes it from other principles like Newton's Laws, Bernoulli's Law, or the Otto cycle, which apply to different systems or processes.
