Due to the planar geometry of cycloalkanes, the carbon - carbon bond angles between two different bonds in the cycloalkanes deviates from the ideal tetrahedral bond angle $(109^{\circ}28')$.
This deviation introduces a strain in the molecule which is called angle strain.
The greater the deviation from the normal tetrahedral angle, greater is the angle strain and lesser is the stability .
Cyclopropane has the maximum angle strain among the cycloalkanes.
Hence d is the correct answer.
