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
In SQL, the execution order of a SELECT statement is such that the ORDER BY clause is processed last, after all other clauses like FROM, WHERE, GROUP BY, HAVING, and SELECT have been executed. This is because the ORDER BY clause sorts the final result set produced by these earlier steps.
