Best answer
The correct choice is (a) True

Best explanation: Image sensors are utilized in a passive manner since they only receive signals. Radio hearing and radio sensors are active sensors since they exhibit both transmission and reception characteristic in wireless systems. Image sensors require direct exposure to the environment whereas radio sensors might operate inside a bag.
