Answer:
B. London would be in danger of flooding.
Explanation:
The "Thames Barrier" is a barrier system that is considered a movable one. During high tide, the barrier is opened while during low-tide, it is closed. It started its operations in 1982 and since then, it has been helpful in preventing floods to the majority of places in London (a city in England).
Clearly, if Thames Barrier failed, then London would be in danger of flooding. Much of this flood would come from the rivers and streams that stretches in most areas of Greater London.
So, this explains the answer.
