Cyclopropane (a) has 3 planes of symmetry (each bisecting a C-C bond and opposite H atoms), so answer is 3.
The compound (b) has 2 chiral centers (carbon atoms with 4 different substituents), so answer is 2.
The compound (c) has 2 chiral centers and no symmetry, so stereoisomers = 22 = 4, answer is 4.
Methane (d) has a center of symmetry at the carbon atom, so answer is 1.
Final answer: 3241
