What is TRUE about initial phase work in this algorithm?

10. What is TRUE about initial phase work in this algorithm?

1. A single run is obtained by merging the first M-1 runs.
2. The next run of M-1 is also merged.
3. Until all initial runs are processed, this step continues.
4. All of the above

Answer: D) All of the above

Explanation:

In case of the initial phase work in this algorithm -

1. A single run is obtained by merging the first M-1 runs.
2. The next run of M-1 is also merged.
3. Until all initial runs are processed, this step continues.
