Question 4027 Deck General

The correct answer is C) Diameter of metal in link in inches. The size of chain is determined by the diameter of the metal used in the individual links, not by the other factors provided. This is a common specification for determining the strength and weight-bearing capacity of a given chain. The diameter of the metal in the links is a direct measurement that indicates the overall robustness of the chain, whereas the other options like links per fathom or weight of the cable are not directly related to the size or strength of the chain itself. The other answer choices are incorrect because they do not directly specify the critical dimension used to classify chain size, which is the diameter of the metal in the individual links.
