1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Both A and R are true and R is the correct explanation of A.

Explanation
The SQL LIKE keyword allows the use of wildcard characters to perform pattern matching. SQL provides two wildcard characters to use with the LIKE operator: the percent sign (%) which matches any string, and the underscore ("_") which matches any single character.
