First of all the original question has a minor error because the "of" before the underlines portion has been excluded. I believe it should be part of the underlined portion.
So the corrected version should look like,
Knowledge of the winter behaviour of emperor penguins has been gained slowly because
of high winds, temperatures around minus 60 degrees Fahrenheit, the fact of round-the-clock darkness and frequently sudden blizzards make the Antarctic habitats of the emperors dangerous places for humans in winter.
A. of high winds, temperatures around minus 60 degrees Fahrenheit, the fact of round-the-clock darkness and frequently sudden blizzards make
B. of high winds, temperatures around minus 60 degrees Fahrenheit, round-the-clock darkness, with frequently sudden blizzards, make
C. high winds, temperatures around minus 60 degrees Fahrenheit, round-the-clock darkness, and frequent sudden blizzards make
D. high winds, temperatures around minus 60 degrees Fahrenheit, the fact of round-the-clock darkness, with frequent sudden blizzards, making
E. high winds, temperatures around minus 60 degrees Fahrenheit, round-the-clock darkness, and frequent sudden blizzards makin
The opening statement states that the "Knowledge of X has been gained slowly because of high winds, blah blah blah". So you mean to say that the knowledge has been gained slowly BECAUSE of high winds? This doesn't even make sense. The knowledge has been gained slowly because some factors make it hard for humans to stay in that region.
Therefore, A & B are out
No need to use the -ing verb form, we dont need to imply any progressive action. Moreover D states, "X,Y, the fact of Z" which is a parallelism error so D is out.
E has no parallelism issue but uses "making" vs "make" so that's out too.
In conclusion, if you eliminate the middlemen the correct sentence will look like this,
The knowledge of X has been gained slowly because A, B, C and D, make the habitats dangerous places for humans - A, B, C and D need to be parallel and follow the same form.
C fixes all the issues.
