Which of the following components prevent(s) objects smaller than 1/4 inch from entering the GE LM2500 gas turbine engine?

Correct Answer: Option B — FOD screens

Foreign Object Damage (FOD) screens are critical protective devices installed at the engine inlet. They are designed to prevent debris larger than 1/4 inch from entering the compressor section. Protecting the compressor is vital, as even small objects can cause catastrophic blade damage and lead to immediate engine failure.
