Emerson said that the poet was landlord, Sealord, airlord. The flight of imagination made the poet master of land, sea and air. But a poet's dream of yesterday becomes today an actual achievement and a reality for all men. Even those who invented, improved and perfected the aeroplane could hardly have dreamt of the possibility of flight into outer space.

The passage best supports the statement that:

A. seemingly impossible imaginations make one a good poet,
B. all imaginations become a reality some day.
C. what man imagined has never been impossible; he has always turned it a reality through his conception of ideas and sheer hard labour.
D. man has reached the climax of technological development with his exploration into outer space.
