The correct answer is: Synergy

Explanation: Synergy occurs when two or more people or things work together to produce a result that is greater than the sum of their individual effects. In the case of the group of people working together to stop malaria, the synergy comes from the fact that they are able to pool their resources, knowledge, and expertise to create a more effective and efficient approach to the problem. This can result in a greater impact on reducing the spread of malaria and improving the health of the population.
