1. The problem asks us to estimate the value of $965 \div 42$. 2. To estimate, round the numbers to values that are easier to divide. 3. Round 965 to 1000 and 42 to 40. 4. Now divide the rounded numbers: $$\frac{1000}{40} = 25$$ 5. This estimate suggests the answer is close to 25. 6. Checking the choices, 25 corresponds to Choice A. 7. Therefore, the best estimate for $965 \div 42$ is $25$.
