To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Multiply corresponding record1 by record2 - This option is not a valid statement because multiplying two records is not a well-defined operation. Multiplication is typically performed on individual values rather than entire records.

Option B) Add corresponding record1 to record2 - This option is a valid statement because adding two records is a valid operation. It involves adding corresponding values from each record.

Option C) Move corresponding record1 to record2 - This option is a valid statement. It suggests moving the values from record1 to record2.
