Skyline Builders and Pine Lumber had a contract, calling for Pine Lumber to deliver a certain quantity of bricks to Skyline's place of business on the first of every month for one year. Pine delivered the bricks one week late for the first six months, but Skyline did not object. When Pine delivered the bricks one week late, as usual, in the seventh month, Skyline attempted to cancel the contract because of the late delivery. Which of the following is true about this scenario?

A. Pine will have to return the delivery fee of the first six months because it broke the contract.

B. Skyline does not have the legal right to modify the contract.

C. Pine is not in breach because the delivery was made at the intended place of business.

D. Skyline has waived its right to cancel the contract.

But the Pine Lumber was always late in his delivery, but Skyline does not have the legal right to cancel the contract at the seventh month because if Skyline had problem, they would have cancelled the contract in the first or second month but they failed to do so.

After receiving the bricks late for 6 months and then cancelling the contract on the seventh month is not legal. If they had they would have cancelled it prior.

Hence, the correct answer is Option B
