Answer: A. ENGAGED IN AN ARMS RACE
Explanation:
Now whilst I'm am not sure what chart you speak of, option A would be the most logical choice because the other choices are simply wrong or not entirely true.
By the year 1914 (year World War 1 began), the British and the Germans had been engaged in an arms race that was most evident in their Navies.
The British had been the dominant navial power for centuries and the Germans wanted to challenge them on that front and decided to build up a modern navy. The British realising this, also invested heavily in their navy, the result of which was an massive increase in battleships and other efficient vessels as well.
