A
melt lead at its melting point
B
heat a unit mass of lead through 1oC
C
change the state of a unit mass of lead at its melting point

change the state of a unit mass of lead at its boiling point
Verified Correct Answer: C.
Physical Principles & Numerical Solution
Specific latent heat of fusion of lead is the amount of heat energy required to change the state of 1 kg (unit mass) of solid lead into liquid lead at its melting point, without any change in temperature.
