Critical Reasoning

Please explain with reasons!!

According to current geological theory, the melting of
ice at the end of the Ice Age significantly reduced the
weight pressing on parts of the earth's crust. As a
result, lasting cracks in the earth's crust appeared in
some of those parts under the stress of pressure from
below. At the end of the Ice Age Sweden was racked
by severe earthquakes. Therefore, it is likely that the
melting of the ice contributed to these earthquakes.
Which one of the following, if true, most strengthens
the argument above?
(A) The earth's crust tends to crack whenever there
is a sudden change in the pressures affecting it.
(B) There are various areas in Northern Europe that
show cracks in the earth's crust.
(C) Evidence of severe earthquakes around the time
of the end of the Ice Age can be found in parts
of northern Canada.
(D) Severe earthquakes are generally caused by
cracking of the earth's crust near the
earthquake site.
(E) Asteroid impacts, which did occur at the end of
the Ice Age, generally cause severe
earthquakes.
