Final answer:
Rime ice forms in stratus clouds at a temperature range of -5 to 0 degrees Celsius, while it forms in upper cumulus clouds at a range of -10 to -20 degrees Celsius.
The correct answer is option a).
Step-by-step explanation:
The formation of rime ice is a process that generally occurs at certain temperatures within cloud formations. For stratus clouds, the temperature range for the formation of rime ice is typically -5 to 0 degrees Celsius.
In contrast, the temperature range for rime ice formation in upper cumulus clouds tends to be colder, commonly -10 to -20 degrees Celsius. Therefore, the correct answer to the question is: a) -5 to 0 degrees Celsius; -10 to -20 degrees Celsius.
The correct answer is option a).
