Suggested Answer:
Box 1:
Fault tolerance is the ability of a service to remain available after a failure of one of the components of the service. For example, a service running on multiple servers can withstand the failure of one of the servers.
Box 2:
Disaster recovery is the recovery of a service after a failure. For example, restoring a virtual machine from backup after a virtual machine failure.
Box 3:
Dynamic scalability is the ability for compute resources to be added to a service when the service is under heavy load. For example, in a virtual machine scale set, additional instances of the virtual machine are added when the existing virtual machines are under heavy load.
Box 4:
Latency is the time a service to respond to requests. For example, the time it takes for a web page to be returned from a web server. Low latency means low response time which means a quicker response.

Disaster Recovery = Cloud service that can be recovered after a failure. Fault Tolerance = Cloud service that remains available after a failure. Low latency = Cloud service that can be access quickly from internet. Dynamic scalability = Cloud service that performs quickly when demand increases.

1️⃣ Fault tolerance → A cloud service that remains available after a failure occurs. 2️⃣ Disaster recovery → A cloud service that can be recovered after a failure occurs. 3️⃣ Low latency → A cloud service that performs quickly when demand increases. 4️⃣ Dynamic scalability → A cloud service that can be accessed quickly from the Internet.

"remains available after a failure" => Fault tolerance "recovered after a failure occurs" => Disaster recovery "when demands increases" => Dynamic scalability "can be accessed quickly" => Low latency

I think it should be fault tolerance, disaster recovery, dynamic scalability and low latency

one way to distinguish them is that 'fault tollerance' relates to the time-interval in which the system is not up, while 'disaster recovery' relates to the time-interval after the system has been brought back up. Does it make more sense this way?
