#$6$ The HSP$\_$TRANSACTIONS table has one row for every transaction. If$,$ and only if$,$ a transaction is a refund to a coverage, it identifies the coverage with the RFND$\_$COVERAGE$\_$ID column. Not all refunds are to coverages, and not all coverages are refunded.

Use the following query to answer the question below it:

SELECT $*$

FROM HSP$\_$TRANSACTIONS

$$ your SQL here $>$ COVERAGE

ON HSP$\_$TRANSACTIONS.RFND$\_$COVERAGE$\_$ID $=$ COVERAGE.COVERAGE$\_$ID

What should replace $$ your SQL here $>$ to return only refunds to coverages?

SELECT ONE OF THE FOLLOWING $(1$ PT$)$

A$.$ LEFT OUTER JOIN

B$.$ INNER JOIN

C$.$ RIGHT OUTER JOIN

D$.$ FULL OUTER JOIN
