Answer:
Mercator projection
Explanation:
Using a flat paper map to represent the sphere that is our planet has always been a challenge. The Mercator projection is one of the most common representation, although we know it is more accurate around the Equator line and the precision diminishes as you get closer to the poles.
There are other types of projections, correcting some issues, but with their own flaws too. The only accurate representation of the planet is a globe, since it matches the shape of the planet.
The biosphere is composed of all living organisms

B. The curtains on the windows of a bedroom.
The rest of the choices are not man-made which would not be infrastructure.
