How many clusters of Alaskan snow crab are available for order?

The selection of 1.5 pounds or 2 clusters is accurate because it reflects the common packaging and portioning of Alaskan snow crab available for sale. When dealing with seafood, especially shellfish like snow crab, it's typical for suppliers to provide options that account for both weight and the number of clusters.

In this case, 1.5 pounds corresponds to approximately two clusters, making it a practical choice for consumers who want a sufficient quantity for meals. This option balances a common weight measurement with the number of clusters, thus serving both those who prefer weight and those who think in terms of serving size.

The other options either present a weight that does not align with typical packaging or specify too few or too many clusters, which are not the standard offering for ordering Alaskan snow crab. Therefore, 1.5 pounds or 2 clusters is the most accurate and commonly accepted choice for ordering Alaskan snow crab.
