Final answer:
The internal temperature for fresh beef is 160°F (71°C), which is considered well-done. It's important to use a meat thermometer to accurately measure the temperature.
Step-by-step explanation:
The internal temperature for fresh beef is 160°F (71°C), which is option C. This temperature ensures that the beef is cooked to a safe temperature and reduces the risk of foodborne illnesses.
When beef reaches this internal temperature, it is considered well-done. However, lower temperatures can also be used for different levels of doneness. For example, medium-rare beef is typically cooked to an internal temperature of around 145°F (63°C).
It's important to use a meat thermometer to accurately measure the internal temperature of the beef. This ensures that it is cooked safely and at the desired level of doneness.
