Detailed Solution

The central C atom in the allene molecule is $sp$ hybridized, and the remaining two C atoms are ${sp}^{2}$ hybridized.
As a result, the central C atom possesses two double bonds, compared to just one double bond for each of the other two C atoms.
There are two unhybridized p orbitals present on the central carbon atom which are mutually perpendicular. These two unhybridized p orbitals are used to form two pi bonds with two adjacent C atoms.
Hence, the planes containing the ${CH}_{2} $ groups are mutually perpendicular.
Thus,

The statements A, B and C are correct.
