The correct answer is option 'c) Solvent', not option 'b) Element'. Let's understand why.

Introduction:
In a solution, which is a homogeneous mixture of two or more substances, there are two main components: the solute and the solvent. The solute is the substance that is present in a smaller quantity and gets dissolved, while the solvent is the substance that is present in a larger quantity and does the dissolving.

Explanation:
1. Solute:
- The solute is the component that is introduced in a smaller quantity into a solution.
- It is the substance that gets dissolved in the solvent.
- The solute can be a solid, liquid, or gas, depending on the type of solution.
- It may or may not be present in all solutions, as some solutions can be pure solvents without any solute.

2. Solvent:
- The solvent is the component that is present in a larger quantity in a solution.
- It is the substance that does the dissolving of the solute.
- The solvent is responsible for establishing homogeneous bonds with the solute particles.
- It can be a liquid, gas, or even a solid in some cases.
- The choice of solvent depends on the nature of the solute and the desired properties of the solution.

Example:
Let's consider an example of a saltwater solution. In this case, salt (solute) is dissolved in water (solvent).
- Salt is the solute, which is introduced in a smaller quantity.
- Water is the solvent, which is present in a larger quantity and dissolves the salt.
- The water molecules surround the individual salt ions and establish bonds with them, resulting in a homogeneous solution.

Conclusion:
In summary, when a foreign substance is introduced into a larger quantity of another substance, the larger substance is known as the solvent. The solvent is responsible for establishing homogenous bonds with the solute, which is present in a smaller quantity. Therefore, the correct answer is option 'c) Solvent', not option 'b) Element'.
