If the service offered does not materialize, this is called?

It depends on the reason.

If both parties in the agreement or one of the party in an service agreement did not comply to & has a dis agreement & decided to cancel it than it is (B) or "Termination" &

If both agreed & if it failed to go through usually by an provider than it is (A) "Reason of Discontent".

:-)

Confused between option A & B. I am not so sure about it...

A

Season of discontent

It's Option 'A'. 

option A

If the service offered does not materialize, this is called

B. Termination

Although the question is a bit confusing, I would opt C

My best guess is A. This is a question that would best suit those in the business administration/accounting/finance fields.

I would say the best answer is

A. Season of discontent

I go with A) Season of Discontent 

Some one is unhappy that the goods did not came in..

it is not a termination, the contract has not been terminated only the goods have not arrived at this point of time

It is not a Value Breakdown, since the value of the goods have not changed
