B. New attributes may be added from the HTTP response headers, but no headers are ever removed

C. Attributes do not change

D. Previous attributes are passed unchanged

A. Attributes are replaced with new attributes from the HTTP Request response (which might be null)

Explanation:
Attributes are replaced with new attributes from the HTTP Request response.

MuleSoft Doc Ref : Handling Errors During Batch Job | MuleSoft Documentation The default is all processing will stop but we can change it by Max Failed Record field.
General -> Max Failed Records: Mule has three options for handling a record-level error:
Finish processing, Continue processing and Continue processing until the batch job accumulates a maximum number of failed records. This behavior can be controlled by Max Failed Records.
The default value is Zero which corresponds to Finish processing.
