In this question, we are given a list of Earth`s spheres (List-I) and their main constituents (List-II). We need to match the spheres with their correct constituents.

Let`s analyze each option:

Option 1: A-1, B-2, C-3, D-4

According to this option, the lithosphere (A) is matched with living objects (1), but this is incorrect. The lithosphere refers to the solid outer part of the Earth, which includes the crust and upper mantle. The main constituent of the lithosphere is soil, so the correct match for A would be 4. Therefore, this option is incorrect.

Option 2: A-4, B-2, C-3, D-1

According to this option, the lithosphere (A) is correctly matched with soil (4), so it seems promising. The other matches also line up correctly. So, we can continue considering this option.

Option 3: A-1, B-3, C-2, D-4

According to this option, the lithosphere (A) is again matched with living objects (1), which is incorrect. So, this option can be eliminated.

Option 4: A-4,
