Assertion $A :$ Photodiodes are preferably operated in reverse bias condition for light intensity measurement.
Reason $R$ : The current in the forward bias is more than the current in the reverse bias for a $p - n$ junction diode.
In the light of the above statement, choose the correct answer from the options given below :

$(I)$ move $A$ to the right along $X$-axis closer to $B$
$(II)$ move $A$ to the left along $X$-axis away from $B$
$(III)$ as viewed from above, rotate $A$ clockwise about $Y$-axis
$(IV)$ as viewed from above, rotate $A$ anti-clockwise about $Y$-axis
Which of the actions will induce a current in $A$ only in the direction shown?
