Which of the following losses does not result in the dissolution of a partnership?

In partnership law, the dissolution of a partnership can occur due to various factors, but not all losses lead to this outcome. In the case of loss of a specific item after its delivery and while under the partnership's ownership, the partnership typically retains its existence despite such loss. This is because the loss is a mere misfortune affecting the partnership’s assets and does not fundamentally alter the agreement or the ability of the partnership to pursue its business.

When a specific thing is lost after delivery, the obligations and liabilities of the remaining partners generally remain intact. The partnership continues to operate and can still engage in business as usual, even if a specific asset is lost. This scenario indicates that the partnership's structure is resilient against such losses, thereby not prompting automatic dissolution.

By contrast, losses that occur before the delivery of a specific item or those involving retained ownership by one of the partners may result in different legal implications regarding responsibilities and partnerships. Thus, answering the question correctly identifies a situation in which a partnership remains intact despite a loss.
