Question

the treaty of paris officially marked the end of the
options: american civil war, spanish - american war, revolutionary war

Explanation:

The Treaty of Paris (1783) officially ended the Revolutionary War (American Revolutionary War), recognizing American independence. The American Civil War ended with the surrender in 1865 and no Treaty of Paris for it. The Spanish - American War ended with the Treaty of Paris (1898), but this treaty dealt with Spain ceding territories, and the context here (with the cannon image related to the Revolutionary War era) points to the Revolutionary War.

Answer:

C. Revolutionary War (assuming the third option is labeled C, with the text "Revolutionary War")
