Answer
(a) Which component is a variable resistor? : C (b) Which component is a thermistor? : A (c) In which component will the resistance decrease when the temperature?: A (d) In which component will the resistance decrease when the light?: B
Explanation
## Step1: Understanding each component symbolBased on electronic symbols, A is a thermistor, B is a light dependent resistor (also known as photoresistor) and C is a variable resistor.## Step2: Figuring out resistance changeThermistors (_symbol A_) have a resistance which depends on their temperature (resistance can increase or decrease with temperature). The resistance in photoresitors (_Symbol B_) decreases with the increase in light intensity, and variable resistors, or potentiometers (_Symbol C_), can have their resistance manually adjusted in a seamless manner.
