Sid contracts to put new kitchen cabinets in Ned's house. Sid repeatedly tries to install the cabinets, but Ned does not grant him access to the house. In this case:

A) Ned is discharged from his duties under the contract because of material breach.
B) the frustration of purpose doctrine applies to discharge the contract.
C) Sid is discharged from his duties under the contract because Ned's prevention of Sid's performance constitutes a material breach.
D) Both Sid and Ned are discharged from their duties because of impossibility of performance.

Material Breach

A significant failure to perform under a contract which permits the other party to either demand performance or terminate the agreement.

Frustration of Purpose

A doctrine in contract law that can discharge the parties' obligations when a change in circumstances makes the contract impossible to perform as originally intended.

Prevention of Performance

Prevention of performance is a situation where one party's actions make it impossible for the other party to fulfill their contractual obligations, potentially leading to legal consequences.
