Answer:
A. to mix in the powder drug that may have settled at the bottom
Explanation:
Most liquid medicines will instruct you to shake the bottle before consumption. Some particles are settled at the bottom so we need to shake them the get the right mix and so that the active ingredients are evenly distributed throughout it.
If we cannot mix or shake the medicine well, the ratio between each particle will not be the same as what the label states. For example, a bottled liquid medicine has 2% white pine extract. In order for this 2% to be evenly distributed, we need to shake the bottled so the particles will not settle at the bottom.
