Twenty-two feet long and 10 feet in diameter, the AM-1 is one of the many new satellites that is a part of 15 years effort of subjecting the interactions of Earth's atmosphere, oceans, and land surfaces to detailed scrutiny from space.
A.satellites that is a part of 15 years effort of subjecting the interactions of Earth's atmosphere, oceans, and land surfaces
B.satellites, which is a part of a 15-year effort to subject how Earth's atmosphere, oceans, and land surfaces interact
C.satellites, part of 15 years effort of subjecting how Earth's atmosphere, oceans, and land surfaces are interacting
D.satellites that are part of an effort for 15 years that has subjected the interactions of Earth's atmosphere, oceans, and land surfaces
E.satellites that are part of a 15-year effort to subject the interactions of Earth's atmosphere, ocean, and land surfaces

That refers to satellites , so verb is are (A,B out)
C- part of ..effort of subjecting how x,y, and z are interacting to ..
are interacting indicates right now but the intention is not right now, So incorrect
Between D and E
D-- What is wrong with D?
Is 'effort for' incorrect idiom???
'that' refers to either effort or 15 years
since verb is 'has', the subject of this verb is effort. It means that effort itself has subjected the interactions to detailed scrutiny. I think intention is to say that the 'effort was to subject the interactions to detailed scrutiny )
