#$10$ One row in the PAT$\_$ENC table represents one patient encounter. One row in the ORDER$\_$MED table represents one medication order.

One patient encounter can have many medication orders but one medication order can only have one patient encounter. In other words, the cardinality of this PAT$\_$ENC to ORDER$\_$MED relationship is one$-$tomany.

You start a query with PAT$\_$ENC. You then add ORDER$\_$MED using a left outer join. What is true about the granularity of the result set before and after adding the ORDER$\_$MED table?

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

A$.$ The granularity changes from one row per medication order to one row per patient encounter

B$.$ The granularity stays at one row per patient encounter

C$.$ The granularity stays at one row per medication order

D$.$ The granularity changes from one row per patient encounter to one row per medication order on an encounter
