JEE Main 2023 Chemistry question

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 :

• (A)Both (A) and (R) are true but (R) is not the correct explanation of (A)
• (B)(A) is false but (R) is true
