The statement that can be attributed to the discoveries made by Schwann is as follows:
The smallest unit of life is the cell.Thus, the correct option for this question is D.
What is the contribution of T. Schwann?The major contribution of Theodore Schwann is that he proposed the Cell theory in 1839. This theory consists of three parts. They are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of life for all living organisms. A Cell is the basic structural and functional unit of life.Apart from this, Cell theory was further refined by German Biologist Rudolf Virchow in 1855. He states that "all cells are arising from pre-existing cells". Option one is given by R. Virchow.
While all animals and plants are made up of cells is the second point of the cell theory. So, the correct option with respect to the question is that a cell is the smallest unit of life.
Therefore, the correct option for this question is D.

2) Earth
Explanation:
Here, the planet A is mars, and planet B is Earth as per the information given here.
What are planets?A planet is basically a celestial body which orbits the Sun. It has enough mass to overcome rigid body forces as well as adopt a hydrostatic equilibrium shape (almost round), has cleared the area in and around its orbit, and is in orbit around the Sun.
A rocky planet is basically the feature of Mars. Volcanoes, impacts, winds, crustal movement, and chemical reactions have all changed its solid surface.
The surface of Earth, a rocky planet along with the mountains, canyons, plains, and other landforms, is solid and dynamic.
Basically, the world is mostly encapsulated with the component namely water.
The only planet in solar system renowned to have liquid water on its surface is Earth, which is the fifth largest planet overall.
