Answer:
B) completeness test.
Explanation:
A completeness test is done to verify that the sales order contains all the appropriate data items. Sometimes the ordering processes are a little complicated, or long, or repetitive, and it is not uncommon for some clients to forget to introduce all the required information. The completeness test is carried out to verify that all the requested information was properly recorded. In this case, the manager of Cezary Foods probably forgot to record his phone number and in order for the purchasing process to be complete, he must fill the missing information.
