Final answer:
Venus is the correct answer as it does not have a global intrinsic magnetic field to generate large-scale auroras like the other planets mentioned.
Step-by-step explanation:
The question asks about which planet does not exhibit auroras. Auroras are natural light displays in the sky, typically seen in the high latitude regions (around the Arctic and Antarctic). They are caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere).
Based on the provided information regarding the atmospheres of the giant planets and their magnetospheres, Jupiter, Saturn, and Neptune all have magnetic fields and atmospheres conducive to auroras, driven by their magnetic fields interacting with the solar wind. However, Venus does not have a global intrinsic magnetic field to interact with the solar wind and produce large-scale auroras, although it has been observed to have auroras generated in other ways.
Therefore, the correct answer to the question is: All of the following planets have auroras except d. Venus.
