Study the given layout of data in a system using $2-$D parity. It is known that even parity is being used by this system. The last row and column $($shaded$)$ contain the parity bits. Answer the questions below with

justification in each case:

Looking just at the row parity bits, can you say whether the data has been correctly received? If not, which rows are in error?

Looking just at the column parity bits, can you say whether the data has been correctly received? If not, which columns are in error?

What minimum extra information do you need to uniquely identify and correct the bits in error?
