The question is a bit confusing, because there's really no such thing as "a parallel
of the Prime Meridian".
The equator is a parallel of latitude. It extends all the way around the Earth.
Every point on it is equal distances from the north and south poles, and has
zero latitude.
The Prime Meridian is a line between the north and south poles. Every point on it
has zero longitude. It passes through every latitude on Earth, and it crosses the
equator, at a point in the ocean about 385 miles south of Accra, Ghana. The two
of them are perpendicular at that point.
It's a meridian, directly opposite the Prime Meridian.
It is a meridian.
Yes it does.

"240 degrees east of the Prime Meridian" places you at 120 degrees west longitude.
