From first law, ∆U=q+W
For adiabatic process, q=0
∆U=W

Work is path function. Consider the pV curve shown below. To reach from initial state 1 to final state 2 , the area under the curve when path A is taken is more than the area under the curve when path B is taken. So, work done is more when path A is adopted. An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties.
Hence, statement I, II and III are correct.
