Specific latent heat requires energy input during constant temperature phase from graph Steps:

• Identify time interval for melting as duration of flat temperature region on graph (latent heat phase).
• Calculate energy supplied E = power × melting time t_melt.
• Convert mass to kg: m = 0.1 kg.
• Compute L = E / m in J/kg. Not enough information: Graph not provided, so melting time t_melt unknown; total 22 s includes pre-melting heating, preventing exact L calculation. Choices cannot be evaluated without graph data.

Final answer: Not enough information.
