Explanation:

To solve this analogy, we need to identify the relationship between the words "yard" and "inch" and then find a similar relationship between the options.

The relationship between "yard" and "inch" is that they are both units of measurement. Specifically, a yard is a larger unit of measurement than an inch. There are 36 inches in a yard.

Analysis of the options:

a) Gallon: A gallon is a unit of measurement for volume, just like a quart. However, a gallon is a larger unit of measurement than a quart. There are 4 quarts in a gallon. Therefore, option A is not the correct answer.

b) Ounce: An ounce is a unit of measurement for weight or volume. In this case, a quart is a larger unit of measurement than an ounce. There are 32 fluid ounces in a quart. Therefore, option B is the correct answer.

c) Milk: Milk is not a unit of measurement, so this option is not relevant to the analogy. Therefore, option C is not the correct answer.

d) Liquid: Liquid is a general term that encompasses different substances, including milk. However, it does not represent a unit of measurement. Therefore, option D is not the correct answer.

Conclusion:

Based on the relationship between "yard" and "inch," the correct answer to the analogy "yard is to inch as quart is to" is option B) ounce.
