Answer:
Correct Answer: 29.partly solid and partly liquid.
Solution:
Formula:
- $O$ to $A \longrightarrow$ material is in solid state (only temperature is increasing).
$A$ to $B \longrightarrow$ material is partially solid and partially in liquid state.
$B$ to $C \longrightarrow$ material is in liquid state.
$C$ to $D \longrightarrow$ material is partially liquid and partially in vapour state.
