The correct answer is - A. Spain most likely would be invaded by sea because the Pyrenees physically isolates Spain from the rest of Europe.

Spain is a very hard country to be invaded by land, and the reason for that are the Pyrenees. The Pyrenees are occupying all of the space that connects Spain with the rest of Europe. The mountains are high, and also an excellent strategic place for defense, thus trying to invade Spain through it will be the worst option.

On the other hand, big portion of the country is open to the sea, and also its coastline is low, not with cliffs or ragged terrain. Thus invading Spain through sea would be much easier and wiser, as it can be attacked from numerous places at the same time, easily breaking its defense lines and invade it.

The answer should be A.

Spain most likely would be invaded by sea because the Pyrenees physically isolates Spain from the rest of Europe.
