Answer to Question 1

D

Answer to Question 2

Subqueries and joins are both used to process data for queries that require data from multiple tables. Subqueries involve embedding a second query within the WHERE clause of the first query. Many levels of subqueries can exist. Joins involve combining the rows of multiple tables into a single relation whose rows contain the data from all the tables that are joined. This new relation can then be processed by the other clauses of the SELECT query. One notable issue with subqueries is that only data from a single table may appear in the result that is returned by the query. One notable issue with joins is that any unmatched rows in either table will not appear in the result that is returned by the query.
