The plot is fusion curve, i.e solid-liquid equilibrium curve
If we move along the curve from higher pressure to lower pressure, we see that temperature decreases
That is, as pressure is decreased, temperature increases.
This temperature is the melting point
Therefore, as the pressure is decreased, melting point increases.
By analogy, as the pressure is increases, melting point decreases.
so, the answers are option (C) and (D)
