A. B. C. D.A.
According to the CAP theorem, a distributed system can only provide two of the following three guarantees at any given time: consistency, availability, and partition tolerance. Therefore, in scenarios where there are no network partitions, you do not need to make any trade-off between the guarantees, and you can have all three guarantees (consistency, availability, and partition tolerance) simultaneously.
Network partitions occur when a network connection between two or more nodes in a distributed system is lost, and the remaining nodes are unable to communicate with each other. In such scenarios, the system needs to choose between consistency and availability. If the system chooses consistency, it will sacrifice availability, and if it chooses availability, it will sacrifice consistency.
The other options in the answer choices, such as when the system is running in the cloud, on-premise, or using load balancers, do not necessarily affect the need to make a trade-off between the guarantees provided by the CAP theorem. These options are not directly related to the CAP theorem and do not guarantee that a trade-off will not be necessary.
In summary, the correct answer to this question is A. When there are no network partitions, you do not need to make any trade-off between the guarantees provided by the CAP theorem.
