B. Clustering provides fault tolerance.
Nope, I agree with load balancing as if one of the back end servers fails you will have at least one other up and running. The question is about high availability.
D is wrong. Load Balancing can provide SOME availability but no fault tolerance. Load Balancing is mainly used for performance and scale-ability. Clustering is used for fault tolerance and HIGH availability. Load Balancing will not take over if a server fails. It only helps with the load when there is a lot of traffic. So it would be B.
I will go with B.

While load balancing introduces redundancy, it’s not a strategy that alone can provide high availability. Servers sitting behind a load balancer may be running, but that doesn’t mean that they are available!
