Final answer:
Inefficient knowledge transfer is a common disadvantage of virtual teams, stemming from communication barriers and the lack of physical presence, which are intrinsic to remote collaborations.
Step-by-step explanation:
The question is asking about a disadvantage of virtual teams. Among the options provided, inefficient knowledge transfer is often cited as a significant disadvantage. Virtual teams can suffer from communication barriers and lack of face-to-face interaction, which can hinder the transfer of tacit knowledge that is easily shared through informal conversations and observations in a physical workspace. Virtual teams may also experience challenges in building trust among members, which is crucial for effective knowledge sharing and collaboration.
In comparison, limited market opportunities are generally not a direct result of virtual teams, poor leadership is not inherent to virtual teams but can occur in any team, and decreased productivity can be a result of various factors and not necessarily because a team is virtual.
