A company includes a cost adjustment clause for changes in law in a contract. What is its purpose?

Correct answer: Sharing financial risk from legal change

The direct answer is option B: sharing financial risk arising from a change in law. A change-in-law clause says what will happen if a new law, regulation, tax, duty, or mandatory requirement changes the cost of performing a contract. Without such a clause, one party may have to bear an unexpected cost alone. The clause may permit a price adjustment, reimbursement, renegotiation, or another agreed method, so the financial effect is allocated in advance rather than becoming a surprise dispute. Option A, choosing a customer colour, is a design or preference matter, not the purpose of this clause. Option B is correct because it manages and distributes the financial risk created by legal change. Option C, stopping weather, is impossible and unrelated to contracts. Option D, decorating machines, has no connection with legal-cost adjustment. Exam cue: change in law changes obligations or costs; the clause is a contractual risk-management tool.
