Reason (R) Energy can change from one form to another but the total energy is always conserved.
Which of the following is true?

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true, but (R) is not the correct explanation of (A)
• C. $( A )$ is true, but $( R )$ is false
• D. $( A )$ is false, but $( R )$ is true
