Solution:

Option a

We should crash D and H

The cost of crashing per period of H is 1500.
The cost of crashing per period of D is 4000.
The cost of crashing per period of A is 7000.
The cost of crashing per period of B is 6000.

Hence, to crash the project by 5 months we must crash activities D and H which are of the least costs per crash period and can crash the project up to 6 months.
