When there are no errors, how does the Batch Job scope process records within and between the Batch Step scopes?

A Mule application contains a Batch Job scope with several Batch Step scopes. The Batch Job scope is configured with a batch block size of 25.

A payload with 4,000 records is received by the Batch Job scope.

When there are no errors, how does the Batch Job scope process records within and between the Batch Step scopes?
A . The Batch Job scope processes multiple record blocks in parallel, and a block of 25 records can jump ahead to the next Batch Step scope over an earlier block of records Each Batch Step scope is invoked with one record in the payload of the received Mule event
For each Batch Step scope, all 25 records within a block are processed in parallel
All the records in a block must be completed before the block of 25 records is available to the next Batch Step scope

B . The Batch Job scope processes each record block sequentially, one at a time Each Batch Step scope is invoked with one record in the payload of the received Mule event
For each Batch Step scope, all 25 records within a block are processed sequentially, one at a time
All 4000 records must be completed before the blocks of records are available to the next Batch Step scope
C . The Batch Job scope processes multiple record blocks in parallel, and a block of 25 records can jump ahead to the next Batch Step scope over an earlier block of records Each Batch Step scope is invoked with one record in the payload of the received Mule event
For each Batch Step scope, all 25 records within a block are processed sequentially, one record at a time
All the records in a block must be completed before the block of 25 records is available to the next Batch Step scope
D . The Batch Job scope processes multiple record blocks in parallel
Each Batch Step scope is invoked with a batch of 25 records in the payload of the received Mule event
For each Batch Step scope, all 4000 records are processed in parallel
Individual records can jump ahead to the next Batch Step scope before the rest of the records finish processing in the current Batch Step scope

  1. Ans is C
    because Mule sends the record blocks to their corresponding batch step and processes them asynchronously. Each batch step starts processing multiple record blocks in parallel, however, batch steps process the records inside each block sequentially.
