Explanation:

The main topic is about Kodiak bears' habitat. The previous sentence mentions "give the bears lots of room" and the next mentions "Within this huge wilderness". The option "the bears' habitat covers about 5,000 square miles of land" directly relates to the idea of a large habitat (room, huge wilderness). The other options: "it is best to stay away..." is about safety (not habitat), "these bears often walk..." is about behavior (not habitat), "there are five other types..." is about other mammals (not relevant to the main topic of Kodiak bears' habitat size).

Answer:

the bears’ habitat covers about 5,000 square miles of land.
