A. Option A
B. Option B
C. Option C
D. Option D
E. Option E
Answer: A
Explanation:
When there are null values in the columns of the tables being joined, the null values do not match each other. The presence of null values in a column from one of the tables being joined can be returned only by using an outer join (unless the WHERE clause excludes null values).
