Answer:
Option C is correct.
Step-by-step explanation:
The parol evidence rule is a law that determines what kinds of evidence the parties involved in a contract dispute can introduce when trying to determine what is contained in a contract.
The objective of the parol evidence rule is to prohibit the involved parties from introducing any evidence of prior oral agreements that had taken place before or during the time that the agreement was in the process of being reduced to its final form in order to alter the terms of the existing contract.
However, there are exceptions where the patrol evidence rule cannot apply, in a situation whereby it can be proven that there was an error in the contract (in this case 100 instead of 1,000), the rule will not apply. If it can also be proven that the contract was part written and part oral, then the patrol evidence rule will not apply.
