Is hydraulic mean depth, means hydraulic radius?

Hydraulic mean depth is flow area/wetted perimeter answer should be C.

The flow rate don't depend on diameter the change in velocity.

Pressure and velocity of liquid depend upon the diameter of the pipe through which liquid flow.
If the diameter increase pressure will be high and velocity will decrease. In above case diameter is decrease so mean velocity will be high and pressure will also decrease.
If the diameter increase pressure will be high and velocity will decrease. In above case diameter is decrease so mean velocity will be high and pressure will also decrease.

Please, someone explain it in detail.

It explains critical flow characteristics for flow past an irregular surface domain. Hydraulic mean radius is different from the hydraulic radius. This answer is correct. Chemical engineers don't have to deal with this, it is effectual in HYDRAULICS section of CIVIL engineering.
