The correct receiving specification weight for sweet potatoes is not provided, as it may vary depending on industry standards or specific purchaser requirements.
The question regarding the receiving specification weight for sweet potatoes does not provide a factual context to deduce a specific answer, as different sources may have various standards for sweet potato weights. A standard weight for a medium sweet potato can range anywhere between 130 to 170 grams (about 4.6 to 6 ounces), which does not align with the provided options.
Additionally, the industry or purpose (e.g., retail, food service, processing) might dictate different specification weights. Typically, this specification would be defined by the purchaser or a regulatory body, and it would not be found in general knowledge or academic resources.
The reference to tons and pounds provided appears to be unrelated to the specific question asked about sweet potatoes, rather they seem to pertain to conversions between units of weight. Therefore, without specific context or a definitive source, it is not possible to confidently provide the correct answer from the options given (A, B, C, D).
