To solve this question, the user needs to know about the CIMODE parameter in mainframe systems.

The answer is: C. Record Mode

Explanation:

The CIMODE parameter is used in IBM mainframe systems to specify the mode of processing for the target dataset. It can have one of the following values:

• CI (Control Interval) mode: This mode processes the target dataset in control interval format. Control intervals are groups of records that are read and written as a single unit. This mode is useful for datasets with a high number of records.

• CA (Cascade) mode: This mode processes the target dataset in cascade mode, which means that records are read and written in groups of control areas. Control areas are groups of control intervals that are read and written as a single unit. This mode is useful for datasets with a high number of control intervals.

• Record mode: This mode processes the target dataset in record mode, which means that records are read and written one at a time. This mode is useful for datasets with a low number of records.

Since the question asks which mode allows the processing of the target dataset in a record mode, the correct answer is C. Record Mode. Option A is incorrect because it refers to control interval mode, and option B is incorrect because it refers to cascade mode. Option D is incorrect because one of the above options is correct.
