Common-size statements are most closely associated with vertical analysis.

Here's why:

1. Vertical Analysis: This is a method of financial statement analysis in which each entry for each of the three major categories of accounts (assets, liabilities and equities) in a balance sheet is represented as a proportion of the total account. It’s also known as the common-size analysis. Hence, common-size statements are most closely associated with vertical analysis.

2. The Acid Test: This is a type of liquidity ratio which measures the ability of a company to use its near cash or quick assets to extinguish or retire its current liabilities immediately. It has no direct relation with common-size statements.

3. Horizontal Analysis: This is used in financial statement analysis to compare historical data, such as ratios or line items, over a number of accounting periods. This analysis can be performed on absolute amounts and on percentages. This is different from common-size statements.

4. Diagonal Analysis: There's no standard financial analysis known as diagonal analysis in the context of financial accounting.

So, the answer is vertical analysis.
