Final answer:

Step-by-step explanation:
The Ministry of Health (MOH) should consider using the open tendering method for procurement. This method involves announcing the tender publicly and inviting suppliers to make their bids. One of the primary advantages of open tendering is the promotion of fairness and transparency, as it allows any interested supplier to participate. This could lead to more competitive prices and a higher quality of goods or services. However, the disadvantages include the possibility of an overwhelming number of bids, which can make the selection process more cumbersome and time-consuming. Furthermore, the quality of bids may vary significantly, and there may be increased costs associated with evaluating a large number of proposals.
