Programmable Logic Controllers (PLCs) in Operational Technology (OT) environments commonly useLadder Logic, a graphical programming language resembling electrical relay logic diagrams. It’s the most relevant for PLCs due to its widespread use in industrial automation.

Option A:Ladder Logic is the standard for PLC programming, making it the best choice.

Option B:Rust is modern and secure but not typically used for PLCs.

Option C:C is used in some embedded systems but less common for PLCs.

Option D:Python is versatile but not native to PLC programming.

Option E:Java is rare in PLC contexts.
