Which of the following statements is true about the acceleration clause in installment sales contracts?

The statement that the acceleration clause in installment sales contracts is optional and may or may not be included is accurate. An acceleration clause allows the lender or seller to demand the full outstanding balance of a loan or sale if the borrower defaults on the payment terms. However, it is not a mandatory requirement in all contracts; parties involved in the transaction can choose to include or omit this clause based on their agreement.

Including an acceleration clause can provide additional protection to the seller or lender, ensuring that they have the right to collect the entire debt if agreed terms are violated. However, the decision to include such a clause ultimately rests with the parties involved in the contract negotiations, emphasizing its optional nature. This flexibility means that contracts can be tailored to fit the specific needs of the parties involved, which is a fundamental aspect of contract law.
