What type of combustor is used by the GE LM2500 gas turbine?

AI Explanation
The correct answer is C) Annular. The GE LM2500 gas turbine uses an annular combustor design. In an annular combustor, the fuel is injected into an annular (ring-shaped) combustion chamber, where it is mixed with air and burned. This design is more efficient and compact compared to other combustor types like can or can-annular designs. The other options are incorrect because: A) Can-annular has separate can-type combustion chambers arranged in an annular fashion, B) Can has individual can-type combustion chambers, and D) Cannular is not a common combustor type used in gas turbines.
