This is because the key in relationships['jimmy'] is wrong. The first letter "j" should be uppercase. The key in the given dictionary is "Jimmy" and therefore a lowercase "j" will result in a KeyError exception.

Answer:
Option A: Clustering
Explanation:
Computers can be connected through network technology to work as one single system and this technology is known as clustering. Clustering can offer advantages such as load balancing, scalability, high performance parallel processing etc.
Besides, it also enables a system to be highly available. Malfunction of a computer in the cluster won't affect the system as a whole and the system will just maintain its operation as usual to continuous deliver its service to users.
