Parallel axis shift forgotten

Consider a solid circular cylinder of radius 2 meters and height 3 meters of uniform density. If the density of the cylinder is $ρ$ kg/meter $^{3}$ , then the moment of inertia (in kg meter $^{2})$ of the cylinder about a diameter of its base is

A. $48 π ρ$ ✓
B. $43 π ρ$
C. $24 π ρ$
D. $4 π ρ$

You have the answer. Trap Analysis is why the other three were written.
