Final answer:
The statement is true, as small groups have higher internal cohesiveness due to better relationship management and monitoring and reduced collective action problems. Large groups struggle with issues such as free-riding and less effective peer pressure, which can hinder their cohesion.Option A is correct
Step-by-step explanation:
The statement 'To maximize cohesiveness, the team should be as small as possible without jeopardizing its ability to accomplish the task.' is true. Small groups are indeed known for their strong internal cohesiveness, which stems from close-knit interpersonal relationships and easier monitoring and enforcement of group norms. However, when the size of a group becomes too large, collective action problems tend to become more severe due to challenges like free-riding, difficulties in monitoring individual behavior, and diminished peer pressure.
Additionally, in small groups, majority rule is generally more effective, and the strength of personal relationships can help mitigate collective action problems without the need for formal mechanisms. The team halo effect also suggests that teams may appear more effective than they actually are, further supporting the importance of keeping groups optimally small.
