Answer:
O D. It allowed the United States to establish a naval base at Guantanamo Bay.
Step-by-step explanation:
The Platt Amendment was the peace treaty signed by the United States and Cuba regarding the involvement and presence of the American government in the nation. This treaty also agrees to the involvement of the US in Cuban's domestic and foreign affairs.
Named after Senator Orville H. Platt who first introduced the bill in the House, the treaty was also supported by the Governor of Cuba at that time, Leonard Wood. The main provision of the treaty aside from allowing the US into its affairs, Cuba also agreed to lease land to the US for the establishment and maintenance of a naval base in the Guantanamo Bay.
