What is the minimum diameter of a golf ball in inches?

• A. 1.60 inches
• B. 1.70 inches
• C. 1.68 inches
• D. 1.65 inches

Answer: (C)

The main concept is that golf ball size is regulated, with a strict minimum diameter. The smallest allowed diameter is 1.68 inches, a standard set by the governing bodies (USGA and The R&A) to keep play fair and consistent across all balls. If a ball were smaller than this, its performance could vary more and disrupt play; if larger, it would still be legal but would not represent the minimum size the rules require. Among the given options, 1.68 inches is the smallest value that satisfies the rule, while the other numbers are either below the minimum or above it.
