Assertion: When a solid iron ball is heated, the percentage increase in its volume is largest.
Reason: The coefficient of superficial expansion is twice that of linear expansion, whereas the coefficient of volume expansion is three times that of linear expansion.

Explanation:
- The assertion states that when a solid iron ball is heated, the percentage increase in its volume is the largest.
- The reason provided is that the coefficient of superficial expansion is twice that of linear expansion, and the coefficient of volume expansion is three times that of linear expansion.
- Let's examine each part of the assertion and reason separately.

Assertion:
- The assertion claims that when a solid iron ball is heated, the percentage increase in its volume is the largest.
- This is a valid statement because when a solid object is heated, the molecules within it gain kinetic energy and start moving more vigorously. As a result, the intermolecular forces weaken, causing the object to expand. The degree of expansion is greater for the volume compared to other dimensions such as length or area. Therefore, the assertion is correct.

Reason:
- The reason provided states that the coefficient of superficial expansion is twice that of linear expansion, and the coefficient of volume expansion is three times that of linear expansion.
- The coefficient of linear expansion (α) measures the change in length of a material per unit length per degree Celsius change in temperature. The coefficient of superficial expansion (β) measures the change in area per unit area per degree Celsius change in temperature. The coefficient of volume expansion (γ) measures the change in volume per unit volume per degree Celsius change in temperature.
- The reason implies that β = 2α and γ = 3α.
- This relationship between the coefficients of expansion is correct. For example, for a given change in temperature, if the linear expansion is 1 unit, the superficial expansion will be 2 units, and the volume expansion will be 3 units. Therefore, the reason is also correct.

Explanation of the Answer:
- Both the assertion and reason are true.
- The reason provided in the question is the correct explanation of the assertion.
- Hence, the correct answer is option A, which states that both the assertion and reason are correct, and the reason is the correct explanation of the assertion.
