Assertion (A) : Apparent depth may be equal to (Real depth \( \times \mu \) )
Reason (R): If object is in air and the observer is in a medium of refractive index \( \mu \) then the apparen depth is (Real depth \( \times \mu \) ) cirr \% Yarer

b) both \( A \) and \( R \) are true and \( R \) is not the correct explanation of \( A \)
c) A is true, \( R \) is false
d) A is false, \( R \) is true
