To begin, let's examine what the code does and what it prints for each call. The function getet(name="World") defines a parameter with default value "World" and then prints "Hello," followed by the value of name. When greet() is called without arguments, name takes the default value "World", so the first print outputs: Hello, World. Next, greet("Alice") is invoked, so name becomes "Alice" and the second print outputs: Hello, Alice.

Option B states: "Hello, name" and "Hello, Alice". This would require the first print to literally output the string name rather than substituting the variable's value, which does not occur here. Therefore this option is incorrect.

Option C states: "Hello, World" and TypeError. Since both calls provide a valid string for name (default in the first call and an explicit string in the second), there is no TypeError produced. Hence this is wrong.

Option A states: "Hello, World" and "Hello, Alice". This matches the observed behavior described above, where the default parameter value is used on the first call and the explicit argument on the second call. This option correctly reflects the output pattern.

Option D states: "Hello, Alice" only. This would imply that the first call did not print anything or that only the second call produced output, which contradicts the function’s design and its two separate print statements. Therefore, D is incorrect.

In summary, the reasoning hinges on understanding default parameters and string formatting in the print statement. The first invocation uses the default value, yielding Hello, World, while the second invocation supplies the explicit argument Alice, yielding Hello, Alice. The other choices misinterpret how the function substitutes the parameter value or misstate the number or type of outputs.
