The difference that exists between the inner and outer planets is - D. None of the inner planets have rings, whereas all the outer planets have rings.
Planets in the solar system are divided into two groups on the basis of distance from the sun are Inner planets and outer planets. The inner planets are closer to the sun compared to the outer planets.
Inner planets:
- include four planets - Mercury, Venus, Earth, and Mars.
- Also called terrestrial planets
- small and rockier
- very less or no natural satellites
- No rings around them
Outer planets:
- include Jupiter, Saturn, Uranus, and Neptune

Answer:
Option-D
Explanation:
Plasmodesmata are the plasma membrane lined pores present in the cells of the plants. Inside these pores runs a closed tubelike structure which is an extension of the endoplasmic reticulum.
The plasmodesmata allows cell to cell communication which involves symplast mode of transport that is through its cytoplasm.
The small water soluble molecules like amino acid and sugars can easily pass through these plasmodesmata via diffusion. The large molecules can be transported through these plamodesmata through selective diffusion.
Thus, Option-D is the correct answer.
