Final answer:
The contract lacks clarity and specificity.
Step-by-step explanation:
The correct option is b. The contract lacks clarity and specificity.
Although the contract mentions the work to be done, it lacks specific details such as the dimensions, specifications, and materials to be used. This makes it difficult to determine the scope and quality of the work. Additionally, the contract does not specify any timelines or deadlines for completion.
A well-written contract should clearly define the expectations, responsibilities, and conditions for both parties involved. It should be detailed enough to prevent any misunderstandings or disputes, and provide a clear framework for the work to be carried out.
