What are the sizes of iced/blended drinks offered?

The sizes of iced and blended drinks offered in the context of the question align with the common offerings found at many beverage or coffee establishments. Specifically, the answer indicating sizes of 16, 20, 24, and 32 is correct as it reflects a standard sizing format, moving from smaller to larger portions suitable for these types of drinks.

Typically, iced or blended beverages are served in a range of sizes that cater to different consumer preferences, from smaller individual servings to larger options for sharing or for those who prefer a more substantial drink. The inclusion of 32 ounces as the largest size is indicative of a common trend in beverage shops aiming to provide ample choice for customers.

Other size options do not align with frequently encountered size offerings within the beverage industry, which often utilizes these specific measurements in their drinks. Thus, the range of sizes provided by the correct answer fits with the industry standards and customer expectations for iced and blended drink offerings.
