<u><em>The Mir Space Station was in orbit for an astonishing 15 years, being the first modular space station public ally known!</em></u>
The Mir Station is no longer in orbit and was destroyed upon forced reentry by the Russians in an attempt to get rid of it, so it is NOT A.
Does the word "Mir" sound American to you? Well I certainly hope not, because it isn't, so it is NOT C.
If it isn't A, and it isn't C, it can't be all of the above, so it is NOT D.
So the answer is B by process of elimination!
