### Break Down the Problem
1. Understand the `NULLIF` function in SQL.
2. Identify the parameters provided to the function.
3. Determine the output based on the function's behavior.

### Relevant Concepts
The `NULLIF` function takes two arguments and returns `NULL` if the two arguments are equal; otherwise, it returns the first argument. The syntax is:
$$
\text{NULLIF(expr1, expr2)}
$$

### Analysis and Detail
1. In this scenario, the parameters for `NULLIF` are `1` and `1`.
2. Since both parameters are equal (`1 == 1`), the function will return `NULL`.

### Verify and Summarize
- Function call: `NULLIF(1, 1)`
- Both arguments are equal, thus the output is `NULL`.

### Final Answer
The SQL statement `NULLIF(1, 1)` returns: **NULL**.
