1. 110
2. 85
3. 100
4. 120

Answer: 120

The question asks for the product of the resultant of the first and second row. Interpreting the row result as the product of numbers in each row gives \(21\times19\times8=3192\) and \(16\times13\times9=1872\), but the intended exam pattern is a row-operation puzzle; the provided correct option is 120.
