To answer this question, we need to understand the SORT statement in COBOL.
The SORT statement is used to sort records in a file based on specified sort fields. In this case, the SORT statement is:
SORT FIELDS = (1,6,CH,A)
SUM FIELDS = (7,2,PD)
The SORT FIELDS clause specifies the fields to be used for sorting. In this case, it is sorting based on the first 6 characters in ascending order (A). The SUM FIELDS clause specifies the field to be summed, starting from position 7, for a length of 2, and the data type is packed decimal (PD).
Now let's go through each option to understand which one matches the output file B:
Option A) Arun 50 Arun 20 Naveen10 Naveen40 Priya 25 Priya 35 - This option is incorrect because it does not match the sorting and summing criteria specified in the SORT statement.
Option B) Priya 60 Naveen50 Arun 70 - This option is incorrect because it does not match the sorting and summing criteria specified in the SORT statement.
Option C) Arun 70 Naveen50 Priya 60 - This option is correct because it matches the sorting and summing criteria specified in the SORT statement. The records are sorted in ascending order based on the first 6 characters, and the sum of the fields starting from position 7 is calculated.
Option D) Naveen50 Priya 60 Arun 70 - This option is incorrect because it does not match the sorting and summing criteria specified in the SORT statement.
Therefore, the correct answer is option C. The output file B would look like: Arun 70 Naveen50 Priya 60.
