When analyzing this question, I first restate the setup to ensure the behavior is clear: there is a function greet with a default parameter name set to "World". It prints two pieces: the string "Hello," and the value of name.

Option A claims: 'A. "Hello, World" and "Hello, Alice"'. This aligns with how the function calls execute:
- greet() uses the default name, which is "World", so the output line is: Hello, World
- greet("Alice") passes the string "Alice" as the name parameter, producing: Hello, Alice
Thus, both calls produce exactly these two outputs, one per call, in order.

Option B claims: 'B. "Hello, name" and "Hello, Alice"'. This would imply that the literal word name is printed, which would only happen if the parameter value were literally the string "name". Since greet() uses the default "World" and greet("Alice") uses the value "Alice", this option is incorrect.

Option C claims: 'C. "Hello, World" and TypeError'. A TypeError would occur if there were an argument mismatch or a misuse of the function, but the provided calls are valid: greet() with no argument and greet("Alice") with a string argument. Therefore, a TypeError does not occur here, making this option false.

Option D claims: 'D. "Hello, Alice" only'. This would suggest only the second call produced output, or that the first call produced nothing. However, the first call greet() does produce output using the default parameter, so two lines are printed overall. Hence, this option is incorrect.

In summary, each incorrect option contradicts the actual behavior of a function with a default parameter and two valid calls: the first call uses the default value, and the second uses the provided argument.
