JEE Main 2025 Physics question

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : Refractive index of glass is higher than that of air. Reason (R) : Optical density of a medium is directly proportionate to its mass density which results in a proportionate refractive index. In the light of the above statements, choose the most appropriate answer from the options given below

• (1)(A) is correct but (R) is not correctCorrect
• (2)(A) is not correct but (R) is correct
• (3)Both (A) and (R) are correct but (R) is not the correct explanation of (A)
