The correct answer is based on the functionality and versatility of Programmable Logic Controllers (PLCs) in industrial settings. PLCs are designed to interface with a wide range of input types to effectively monitor and control various processes.

Sensors in industrial environments can provide different types of signals: digital (or discrete) signals, which indicate binary states (like on/off), and analog signals, which represent a range of values (like temperature, pressure, or flow). By utilizing both types of input, a PLC can react to complex control systems and implement precise process regulation.

This ability to accept both analog and discrete inputs allows for comprehensive data acquisition and facilitates more advanced automation tasks. As such, the use of both analog and discrete sensors expands the PLC's applicability across diverse industrial applications, enhancing operational efficiency and responsiveness.
