Answer

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

Explanation
In SQL syntax, the GROUP BY clause comes before the ORDER BY clause. The standard order of clauses is SELECT, FROM, WHERE, GROUP BY, HAVING, and ORDER BY. On the other hand, it is true that the ORDER BY clause always follows other clauses, as it comes after the other clauses in the statement.
