What are distinguishing features about Type I nested queries?

Solution
The distinguishing features about Type I nested queries are:
- A Type I nested query does not reference any columns of its outer query.
- A Type I nested query executes one time and generates a table that can be used in a table comparison operator.
The other two options are incorrect. A Type I nested query does not execute one time for each row of its outer query, nor does it reference one or more columns of its outer query. Those characteristics are more typical of Type II nested queries.
