(a) dew condensing on a leaf

(c) ice cream melting

Explanation:

The process which can be reversed by changing the temperature, i. e., by increasing or decreasing the temperature, is called the reversible process.

From the question,

dew condensing on a leaf is a reversible process,

As the water on the leaf can be changed to gaseous state by increasing the temperature.

The process of condensation and evaporation are reversible of each other.

Ice cream melting

The melted ice cream can be solidified again by reducing its temperature, hence, it is a reversible process.

an egg turning hard when boiled and the batter cooking on a hot griddle

They both are irreversible process, and by changing the temperature, we can not get back the original substance.
