Asolution that contains all of the solute it can hold at a given temperature is
a. diluted
b. saturated
c. supersaturated
d. unsaturated

B.  saturated.

Explanation:

The important point here is 'at a given temperature'.   The amount of solute it can hold will vary according to the temperature.

B. saturated

Explanation:

A solution is composed of two constituents , i.e. , solute and solvent .

Where ,

Solute is preset in lesser concentration and solvent is present in higher concentration .

Solution are given a specific name , according to the concentration of the solute and solvent , i.e. ,

1. diluted

2. saturated

3. supersaturated

4. unsaturated

Saturated solution -

They are the type of solution , where the maximum amount of solute is dissolved and further , no more solute can be added , at a given temperature .
