Which instruments are used for perceiving and acting upon the environment?OptionsSensors and ActuatorsPerceiverNone of the mentioned Sensors

The correct answer is "Sensors and Actuators". These are the instruments used for perceiving and acting upon the environment.

Step 1: Understanding the question The question is asking about the instruments that are used to perceive (detect or measure) and act (do something in response) upon the environment.

Step 2: Evaluating the options

• Sensors: These are devices or modules that can detect or measure physical properties. They are used to perceive the environment. However, they do not act upon the environment.
• Actuators: These are devices that can move or control a mechanism or system. They are used to act upon the environment. However, they do not perceive the environment.
• Perceiver: This is not a specific instrument and does not provide a clear answer to the question.
• None of the mentioned: This option suggests that none of the above options are correct. However, as explained, sensors and actuators are indeed used for perceiving and acting upon the environment.

Step 3: Selecting the correct answer The correct answer is "Sensors and Actuators" because sensors are used to perceive the environment and actuators are used to act upon the environment.
