Suspensions are liquids in which the drug is dissolved.

Explanation:
Suspensions involve solid drug particles dispersed in a liquid without dissolving. The drug in a suspension is not dissolved; the particles are dispersed and can settle to the bottom if left standing. That’s why these products are typically shaken before use to re-disperse the solids and ensure a uniform dose. A solution, by contrast, has the drug dissolved at the molecular level and remains uniform without agitation. A suspension is not a gas, so that option also doesn’t fit.
