Assertion: A solution of table salt in a glass of water is homogeneous.

Reason: A solution having different composition throughout is homogeneous.

The correct answer is option 'C', which states that Assertion (A) is true, but Reason (R) is false.

Explanation:

Homogeneous Solution:
- A homogeneous solution is a mixture that has the same composition and properties throughout its volume.
- In a homogeneous solution, the solute particles are uniformly distributed in the solvent, resulting in a single phase.
- A good example of a homogeneous solution is a solution of table salt in water.

Assertion (A): A solution of table salt in a glass of water is homogeneous:
- This statement is true.
- When table salt (sodium chloride, NaCl) is dissolved in water, the salt particles separate and disperse throughout the water.
- This results in a uniform distribution of sodium and chloride ions in the water, creating a homogeneous solution.
- The solution appears clear and transparent, indicating that it is homogeneous.

Reason (R): A solution having different composition throughout is homogeneous:
- This statement is false.
- A solution with different composition throughout its volume is heterogeneous, not homogeneous.
- In a heterogeneous solution, the solute particles are not uniformly distributed in the solvent, resulting in multiple phases.
- Examples of heterogeneous solutions include suspensions, colloids, and emulsions, where the solute particles are visibly separated from the solvent.

Conclusion:
- The reason provided in the statement is incorrect because a solution with different composition throughout is not homogeneous but heterogeneous.
- However, the assertion is correct as a solution of table salt in water is indeed homogeneous.
- Therefore, the correct answer is option 'C' – (A) is true, but (R) is false.
