Final answer:
Theodore Roosevelt commanded the Rough Riders during the Spanish-American War in Cuba, leading charges up San Juan Hill and Kettle Hill, and achieving significant recognition for his leadership.
Step-by-step explanation:
Commander of the Rough Riders in Cuba
The force known as the Rough Riders in Cuba during the Spanish-American War was commanded by Theodore Roosevelt. Initially under the leadership of Colonel Leonard Wood, the Rough Riders became known for their heroic charges up San Juan Hill and Kettle Hill, despite the disadvantage of being largely without their horses, which they had to leave behind due to transport limitations. Nonetheless, Theodore Roosevelt's fame was cemented with his rugged and enthusiastic leadership of the charge at the battle of San Juan, notably documented in his memoir, "The Rough Riders." Although the Rough Riders achieved significant notoriety, it is important to acknowledge that the African American regiments, known as Buffalo Soldiers, were also critical to the success of the battles in Cuba, providing essential tactical support and some even receiving the Medal of Honor for their valor.
The option that corresponds to the correct answer of who commanded the Rough Riders in Cuba is (d) Theodore Roosevelt.
