Assertion (A): The control system which operates on the time basis is ...
The control system which operates on the time basis is an open loop system. For example, in automatic control of traffic, the time for each lamp (red, yellow and green) is fixed. The operation of each lamp does not depends upon the density of the traffic but depends upon the fixed time. Hence, assertion is true.
Reason is also true but, it is not the correct explanation of assertion.
Reason is also true but, it is not the correct explanation of assertion.

Assertion (A): The control system which operates on the time basis is ...
Explanation:
The given assertion and reason are both true. However, Reason (R) is not the correct explanation of Assertion (A). Let us understand why this is the case.
Open Loop Control System:
In an open loop control system, the control action is independent of the output. This means that there is no feedback loop in the system. The control system operates on the time basis and there is no provision for error detection or correction. Examples of open loop systems include washing machines, traffic signal systems, etc.
Field Control DC Motor:
A field control DC motor is an example of an open loop system. In a field control DC motor, the control action is based on the input voltage and current. The motor speed is dependent on the voltage and current applied to the motor. There is no feedback mechanism to adjust the voltage or current based on the motor speed. Therefore, a field control DC motor is an open loop system.
Assertion and Reason:
The given assertion states that the control system which operates on the time basis is an open loop system. This is true, as we have seen in the definition of an open loop system. The reason states that a field control DC motor is an example of an open loop system. This is also true, as we have seen in the definition of a field control DC motor. However, the reason does not provide a correct explanation for the assertion. The reason only provides an example of an open loop system, but it does not explain why a control system operating on the time basis is an open loop system.
Therefore, the correct answer is option B - Both A and R are true but R is not the correct explanation of A.
The given assertion and reason are both true. However, Reason (R) is not the correct explanation of Assertion (A). Let us understand why this is the case.

Therefore, the correct answer is option B - Both A and R are true but R is not the correct explanation of A.
