Answer:
Explanation:
Please see the attached image of the alarm
Options for the given question
A) electrical --> heat --> sound
B) electrical --> light --> sound
C) electrical --> chemical --> light
D) chemical --> electrical --> mechanical
Solution -
The alarm shown in this picture is a digital alarm in which the chemical cells are the major source for storing electrical energy. These chemical cells then provide stored electrical energy as chemical energy which is again converted into electrical energy and as the alarm rings, the electrical energy is converted into sound energy.
Thus, the energy transformations taking place are as follows –
electrical energy -- Chemical energy -- Sound energy.
Hence, option C is correct
