Answer:
Solutions are always homogeneous.
Explanation:
Solution:
Solution are considered homogeneous because in solution the ratio of solute and solvent remain the same throughout the solution. Both solute and solvent are chemically combined and form a new substance.
In solution the particles of solute can not be seen through naked eye.
When the light is passed through the solution it can not scattered.
Example:
When salt is dissolve in water it makes a solution.
The solution also exist in gaseous form. For example oxygen and many other gases dissolved in nitrogen also form a solution.
Mixture:
In mixture substance are physically combined. In mixture every every individual particle retain their properties.
It can be consist of solid, liquid and gas.
Examples:
Sand in water is also a mixture.
Oil in water form mixture.

Multicellular organism contain different types of cells. The different cells differentiate to perform a particular function. The division of labor property is well shown by the multi cellular organism. The cells of the multi cellular organism must show differentiation process.
Thus, the correct answer is option (d).
