Answer: A. 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed = 4.56 J
m = mass of substance = 123 g
c = specific heat capacity = ?
Change in temperature ,
Putting in the values, we get:


The specific heat of a 123 g substance that requires 4.56 J of heat in order to increase its temperature by 12.32 °C is 
This is my theory of the answer
Multiply the weight of the object by the distance it traveled to find the amount of work output. For the example: 10 lbs. x 1 foot = 10 foot-pounds. Find the work efficiency by dividing the work output by the work input and multiplying by 100.
