The answer is 2.

The heat of hydration decreases with increasing atomic size.

With the increase in size, the charge density decreases, means it will attract solvent molecules to a lesser extent as compared to a small atom which has a high charge density.

Hope U get it.

The quality of a person's life is in direct proportion to their commitment to excellence, regardless of their chosen field of endeavor.

It is during our darkest moments that we must focus to see the light.
