Final answer:
Elizabeth cannot successfully sue unless she can prove that Phillip's statements regarding the business's profits became a term of their contract.
Step-by-step explanation:
The correct statement is d. Elizabeth cannot successfully sue unless she can prove that Phillip's statements regarding the business's profits became a term of their contract.
In this scenario, Phillip's statement about the expected earnings of the business was made during pre-contractual negotiations.
However, this statement does not automatically become a term of their contract.
Elizabeth would need to show that both parties intended for this statement to be a contractual term and that it was relied upon by her in making the decision to purchase the business.
It is important for parties involved in negotiations to clearly outline the terms of the contract in writing to avoid misunderstandings and disputes.
