What is the lifespan range for mice?

• A. 1-3 years
• B. 2-4 years
• C. 3-4 years
• D. 18-24 months

Answer: (A)

Mice generally have short lifespans, with most individuals living about 1 to 3 years depending on strain and care. This broad range captures both younger mortalities and the older ages achievable in well-managed colonies. The other options either exclude older mice who can reach up to around three years or set minimums that are longer than what is typical for many mice. So the best answer that reflects common experience across contexts is 1-3 years.
