Answer 1

C. Boundary beyond which trees cannot grow.

Step-by-step explanation:

You have not provided the text you were given, but I can answer your question anyway.

The term tree line refers to the boundary beyond which trees cannot grow. Before the line, you can encounter at least some species of trees, but after it, there are none. This is usually caused by environmental conditions trees can't survive in, such as extremely low temperatures, too much snow, or lack of moisture.
