Solution

The correct option is B increases
We first note that at the bottom of the lake, the pressure is high (because pressure increases with depth).
Also note that since temperature is given to be constant so Boyle's law is applicable.
Now we see that since PV = constant, and as the bubble goes up, pressure decreases so volume must increase.
