Answer :
Final answer:
The uncertainty of the measurement using a K thermocouple at 60°C according to ASTM E230 standards can vary and is not able to be determined from the options provided in the question.
Explanation:
If a standard type K thermocouple is used to measure a temperature of around 60°C, the uncertainty of this measurement according to ASTM E230 standards could vary. However, the mentioned options in the question are not enough to determine the exact uncertainty since the ASTM E230 standard provides different uncertainty ranges depending on the measurement conditions. Please refer to the ASTM E230 standard document for precise uncertainties at different temperature ranges.
