A. but when up high, atmospherically they - when clause is not directly linked to IC.
B. however, it is in the upper atmosphere in which it may - eliminated as pronoun can’t be singular
C. but in the upper atmosphere, they — no error
D. however, but once in the upper atmosphere it is known to same as B
E. as in the upper atmosphere they - as will remove the contrast and meaning gets awkward.
