`theta` is the optical rotation produced by sugar solution of concentration C and taken in a glass tube of length 0.2 m and radius `r`. Then the solution is transferred to another glass tube of length 0.3 m and radius `r` and the remaining space is filled with distilled water. The optical rotation produced by this solution is

A

`3 theta`

B

`2 theta`

C

`theta`
