In a measuring system quantity under measurement is termed as
Measurand
Controllers
Sensors
Indicators
Measurand
Quick Summary: In any instrumentation or measurement system, the physical parameter, property, or condition that is intended to be measured is officially defined as the 'measurand'. It represents the input to the measurement system.

Measurement=True Value+Error
S=ΔInputΔOutput — where S is sensitivity
The measurement system operates by converting the 'measurand'—the input variable—into a readable or quantifiable output format. This typically involves a chain comprising a sensor (transducer), signal conditioning units, and an indicator/display device.
The measurand is the specific quantity being measured (e.g., pressure, temperature, flow rate).
Measurement is the process of comparing an unknown measurand with a known standard.
The sensor is the first element that responds to the measurand.
Provides a standardized terminology for engineering communication.
Ensures clear identification of system inputs.
Process control industry
Laboratory instrumentation
Automotive sensor systems
Controllers: Devices used to maintain the output at a desired value or setpoint.
Sensors: The primary sensing element that detects the measurand and converts it to a usable signal.
Indicators: Devices that provide a visual representation of the measured quantity to the observer.
A is correct — The quantity intended to be measured in a system is technically known as the measurand.
Always differentiate between the 'measurand' (input) and the 'transducer' (the component that measures it); examiners often swap these in definitions.
