Which of the following are mutually binding project documents? (Select two.)

A quotation is a one-sided pricing offer provided by a seller; it becomes binding only if formally accepted, so in isolation it is not mutually binding.

A letter of intent signals a formal commitment between parties to proceed under defined terms and creates mutual obligations, making it a legally recognized binding document even before a full contract is executed.

A proposal is a non-binding document submitted to request consideration for work; it represents intent to bid, not a mutual agreement.

An evaluation is an assessment document used in vendor selection or performance review; it does not constitute a mutual agreement between parties.

A warranty is a guarantee from one party (seller/manufacturer) to another, but it is a unilateral obligation rather than a mutually negotiated and binding agreement in the project management sense.

The project charter is signed by the project sponsor and authorizes the project, binding the organization to provide resources and the project manager to deliver stated objectives - creating mutual accountability between both parties.
