Final answer:
The correct label for a 3-year-old sheep that was sold as a "spring lamb" is "Lambkin". Hence the correct answer is option D
Step-by-step explanation:
The correct answer is d) Lambkin.
The term "spring lamb" refers to a young sheep that is less than a year old. If the lamb you bought was 3 years old, it would not be considered a lamb anymore, but rather a mature sheep. The term "lambkin" is a cute or affectionate term for a lamb.
For example, if you bought a "spring lamb" that was actually 3 years old, it would be labeled as a "mature" sheep and not a "lambkin".
