Given:
Mass of solid = 5g
Heat required to change into liquid at the same temperature = 30 cal

To find:
Latent heat of fusion in cal/g

Formula:
Latent heat of fusion = Heat / Mass

Calculation:
Using the formula, we can calculate the latent heat of fusion.

Latent heat of fusion = 30 cal / 5g
Latent heat of fusion = 6 cal/g

Therefore, the latent heat of fusion is 6 cal/g.

Hence, the correct answer is option C.

For changing a solid into liquid, heat has to be supplied and this change occurs at constant temperature. Q = mL
⇒ 30 = 5L
⇒ L = 6 cal/g,
