Which countries were part of the Triple Entente during World War I?

The correct answer highlights the core alliance known as the Triple Entente, which consisted of the British Empire, France, and Russia during World War I. This alliance was formed in response to the threats posed by the central powers, primarily Germany and Austria-Hungary. The Triple Entente was not a formal military alliance like the Triple Alliance but rather a series of agreements that established understanding and cooperation among the three nations.

The British Empire provided significant naval strength and vast resources, France contributed a powerful army and industrial capabilities, while Russia added considerable manpower and a different frontline against the Central Powers. Their collaborative efforts were essential in shaping the battles and strategies during the war.

The other options represent either different alliances or countries that were not part of the Triple Entente. For instance, the second choice lists the Central Powers, while the third includes Russia but mixes it with the opposing nations and the Ottoman Empire, which sided with the Central Powers. The fourth option mentions contributions from the Commonwealth nations, which were indeed involved in the war but did not form part of the Triple Entente as an alliance. Understanding this structure of alliances is crucial for comprehending how the war developed and the dynamics between the countries involved.
