Given information:
- A can complete a piece of work in 10 days.
- B can complete the same piece of work in 20 days.
- A and B start the work together.

Approach:
To find out how long it will take for B to complete the remaining work after A leaves off, we need to calculate the work done by A and B in the first 5 days. Then we can determine the remaining work and the time taken by B to complete it.

Calculating the work done by A and B in the first 5 days:
- A completes 1/10th of the work in a day.
- Therefore, in 5 days, A would have completed 5/10th or 1/2 of the work.
- B completes 1/20th of the work in a day.
- Therefore, in 5 days, B would have completed 5/20th or 1/4 of the work.

Calculating the remaining work:
- The total work can be represented as 1.
- A completes 1/2 of the work in 5 days.
- Therefore, the remaining work is 1 - 1/2 = 1/2.

Calculating the time taken by B to complete the remaining work:
- We know that B completes 1/4th of the work in a day.
- Let's assume B takes 'x' days to complete the remaining work.
- Therefore, B completes 1/4th of the work in 'x' days.
- So, 1/4 * x = 1/2.
- Multiplying both sides by 4, we get x = 2.

Conclusion:
After A leaves off, B will take 2 days to complete the remaining work. Therefore, the correct answer is option 'A': 5 days.
