Which of the following statements correctly distinguishes between a Cost-Plus Contract and an Escalation Contract?

Cost-Plus Contracts - Also known as cost reimbursement contracts, where the buyer (contractee) covers the contractor's allowable costs (direct/indirect) plus an additional profit fee (fixed or percentage). It is ideal for projects where the scope is not fully defined, such as, long-term construction, or when accurately estimating costs is difficult. The contractee assumes the risk of cost overruns, while the contractor is protected.   Escalation Clause contracts include a clause (or escalator clause) in a contract that enables an automatic or negotiated increase in the contract price if specific costs (e.g., raw materials, labor) rise beyond a certain, pre-agreed threshold. Thisprotects contractors from price surges due to inflation or shortages during long-term projects. Such clauses are primarily used in construction for volatile materials like steel, fuel, or timber. It helps contractor avoid loss due to market price fluctuations.   While a cost-plus contract pays for all costs, an escalation clause is a specific provision within a contract to handle price fluctuations of specific inputs.
