Hello Experts can you please help me with the question. My only point of confusion is option B and D. If possible could you please explain why the usage of were is correct in option B ?

Hi
yashmatai,
The author believes that (all) the ice of Greenland and Antarctica
is not actually going to melt (about that "all": it seems that the author is talking about either all the ice or a significant amount of the ice there, as 100+ feet is a lot). In this sentence, the author is exploring a (hypothetical) situation in which all the ice in Greenland and Antarctica melted. In such (hypothetical) cases, if we choose to use a
be form (the
be forms are
be,
is,
am,
are,
was,
were,
been, and
being), we are restricted to
were,
even if the subject is singular. This is something that we must remember, as the exam does seem to test this concept.
1.
If the ice melts, something will happen. ← The author thinks that it is possible for the ice to melt.
2.
If the ice were to melt, something would happen. ← The author does
not think that it is possible to the ice to melt.
