Which code correctly loads the package seaborn with the alias sns?

The code that correctly loads the package seaborn with the alias sns is the one that uses the syntax suited for importing a module in Python. In Python, the keyword "import" is used to bring a module or package into the current namespace, and the "as" keyword allows you to give it an alias for easier reference within your code.

By using "import seaborn as sns," you are importing the entire seaborn package and assigning it the alias "sns." This simplifies subsequent references to seaborn functions, as you can now use "sns" instead of writing out "seaborn" each time.

The other options do not correctly fulfill that requirement. Importing a specific function like "scatterplot" does not load the entire package or set an alias for it. Importing "sns" as "seaborn" reverses the intended aliasing, which can lead to confusion or errors when trying to use "sns" in the code. Lastly, "library(seaborn)" is syntax used in R, not Python, making it an incorrect option for this context.
