Assertion :New York City may submerge due to global warming. Reason: Due to global warming, glaciers are melting and due to this, sea-level will be certainly increasing which may cause flooding of cities situated at the banks of the seas. New York is one of them.

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Over the past century, the burning of fossil fuels and other
human and natural activities have released enormous amounts of heat-trapping
gases into the atmosphere.
These emissions have caused the Earth's surface
temperature to rise and the oceans absorb about 80 per cent of this additional
heat.
The rise
in sea levels is linked to three primary factors, all induced by this ongoing
global climate change. One of them is the melting of glaciers and polar ice caps.Large
ice formations, like glaciers and the polar ice caps, naturally melt back a bit
each summer. But in the winter, snows, made primarily from evaporated seawater,
are generally sufficient to balance out the melting.
Recently, though persistently higher temperatures caused by global warming have led to
greater-than-average summer melting as well as diminished snowfall due to later
winters and earlier springs.
Hence, option A is correct.
