Hi. You didn't show what the above question wants. This makes it difficult for me to answer it. However, when searching for this question, I was able to find another question just like yours, which asked you to show which of the answer options could correct the expression " too cold to support life, and with 60 square miles of water tho...". So, I hope this answer can help you.
Answer:
(B) Europa has long been considered far too cold to support life, its
Step-by-step explanation:
The answer option presented above is the only one capable of correcting the sentence shown in the question above. This is because the clause "“its 60 square miles of water thought to be..." is placed as a modifier that has the ability to present a justification for the previous clause. In this case, this clause needs to use a word that refers directly to the word it is justifying. In this case, it is best to replace the words "and with" after the comma with "it."
