  2. Explicit Join ( record-required 0 = true, record-required 1 = true )

  3. Explicit Join ( record-required 0 = false, record-required 1 = true )

  4. Explicit Join ( record-required 0 = true, record-required 1 = false )

C Correct answer

Setting record-required 0 to false allows unmatched records from In0 to pass through (like a left outer join), while record-required 1 = true requires matches from In1. This gives all matching records plus unmatched In0 records.
