The statement that explains why the Thirteenth, Fourteenth, and Fifteenth Amendments were added to the Constitution is: the Union winning the Civil War, ultimately abolishing slavery within the whole country.

The correct answer is: the Union winning the Civil War, ultimately abolishing slavery within the whole country.

To arrive at this answer, we need to understand the historical context of the Thirteenth, Fourteenth, and Fifteenth Amendments. These amendments were added to the U.S. Constitution after the Civil War, which was fought between the Northern Union states and the Southern Confederate states.

The Thirteenth Amendment, ratified in 1865, abolished slavery and involuntary servitude in the United States. This was a direct result of the Union's victory in the Civil War, which aimed to ultimately end slavery throughout the country.

The Fourteenth Amendment, ratified in 1868, granted citizenship to all persons born or naturalized in the United States, including African Americans. It also guaranteed equal protection under the law, ensuring that states could not deny individuals their basic rights.

The Fifteenth Amendment, ratified in 1870, prohibited the denial of voting rights based on race, color, or previous condition of servitude. This amendment aimed to secure the right to vote for African American men, as they had previously been denied this fundamental right.

Therefore, the statement explaining why the Thirteenth, Fourteenth, and Fifteenth Amendments were added to the Constitution is "the Union winning the Civil War, ultimately abolishing slavery within the whole country."
