Answer:
The correct answer is "showing little or no change"
Step-by-step explanation:
According to the context of the sentence, the word "static" means showing little or no change since the "air temperature" was not changing.
The rest of the options are not correct due to the context of the sentence:
The definition "socially bound by tradition" is another definition of static but related to the field of phychology.
The definition "atmospheric electricity" is related to the electricity field.
And finally, the definition "lacking vitality" is used to describe lack of development in a character of a novel for example.
