Why can the limit of partners' investment be written in the deed?

Correct answer: To control capital contribution

Direct answer: Option A, to control capital contribution. Capital contribution means the money or other value brought into the firm by each partner. A deed may state the amount, limit, timing and method of contribution. Step by step: first, the partners decide how much capital is needed; second, the deed records each partner’s responsibility; third, this prevents confusion and helps maintain accurate capital accounts. Option A is correct because an investment limit controls or plans the capital entering the business. Option B is wrong because hiding profit is dishonest and unrelated to capital limits. Option C is wrong because accounts must be maintained, not erased. Option D is wrong because customer management is not the purpose of an investment clause. The exact effect depends on the wording of the deed, but the question asks for its basic purpose. Memory cue: investment limit means “how much capital may be contributed.”
