An LDR's resistance changes with light intensity, while a thermistor's resistancce changes with temperature.
In dark, LDR's resistance is large and in the day/light LDR's resistance is small.
At low temperature, thermistor's resistance is large, while at large temperature it resistance is small.
In an LDR Resistance increases as light intensity falls, while in a thermistor resistance falls as temperature falls.

Answer:
C: You must know force and distance to calculate both.
Explanation:
A force is said to have done work, when it has succeeded in causing displacement in an object from its starting point.
Power can be defined as the rate of doing work.
The work can be calculated using the following formula:
Work done = Force × Displacement
The power can be calculated using the following formula:
Power = Work \ Time
In order to calculate the work and power, the force and distance should be known. The force and distance will help in the calculating the work, which will in turn help in the calculation of the power of the object.
Hence, the answer is you must know force and distance to calculate both.
