Both $(A)$ and $(R)$ are true and $(R)$ is the correct explanation of $(A)$

(C) Silica gel is a well-known adsorbent used to remove moisture from the surrounding environment.In expensive scientific instruments,it is placed in watch-glasses or semipermeable bags to adsorb water vapor from the air.By adsorbing moisture,it prevents the corrosion of metallic parts and protects sensitive electronic components from malfunctioning due to humidity.Therefore,both the Assertion $(A)$ and the Reason $(R)$ are true,and $(R)$ is the correct explanation of $(A)$.

Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$.
Assertion $(A)$: In expensive scientific instruments,silica gel is kept in watch-glasses or in semipermeable membrane bags.
Reason $(R)$: Silica gel adsorbs moisture from air via adsorption,thus protects the instrument from water corrosion (rusting) and/or prevents malfunctioning.
In the light of the above statements,choose the correct answer from the options given below:
