Which of the following statements is incorrect?

a- The Antarctic continental region extends over 14 million square kilometers and comprises 26 percent of the world’s wilderness area.
b- The Antarctic also extends to a further 36 million square kilometers of ocean.

Neither of them is incorrect.

The Antarctic continental region extends over 14 million square kilometers and comprises 26 percent of the world’s wilderness area, representing 90 percent of all terrestrial ice and 70 percent of planetary fresh water. The Antarctic also extends to a further 36 million square kilometers of ocean. It has a limited terrestrial life and a highly productive marine ecosystem, comprising a few plants (e.g. microscopic algae, fungi, and lichen), marine mammals, fish, and hordes of birds adapted to harsh conditions, as well as the krill, which is central to the marine food chain and upon which other animals are dependent.
