Answer:
b, c
Step-by-step explanation:
Remember, the number of order is quite large over 10 million. Therefore, the best step to carry out is
1. Export in multiple batches: This implies that instead of trying to export the whole batch at once, which might not be possible it is best to export in fewer batches.
2. Use PK Chunking: This method involves the use of an automated system that reduces large orders into smaller chunks.
