The following are the steps for a correlated subquery, listed in random order: 1) The
WHERE clause of the outer query is evaluated. 2) The candidate row is fetched from the
table specified in the outer query. 3) The procedure is repeated for the subsequent rows of
the table, till all the rows are processed. 4) Rows are returned by the inner query, after
being evaluated with the value from the candidate row in the outer query. Identify the option
that contains the steps in the correct sequence in which the Oracle server evaluates a
correlated subquery.
