Given Information:
- M and N have four children: P, Q, R, and S.
- P and R are married.
- P has a child named X.
- R has a child named Y.
- Y is a legitimate child of W.

Analysis:
Let's analyze the given options one by one to determine which one is necessarily false.

a) M is the grandmother of Y:
- Since P is married and has a child named X, M can be the grandmother of X.
- Since R is married and has a child named Y, M can also be the grandmother of Y.
- Therefore, option a) is true.

b) R is the father of Y:
- Given that R has a child named Y, it is true that R is the father of Y.
- Therefore, option b) is true.

c) W is the wife of R:
- The given information states that Y is a legitimate child of W, which means that W is either the mother or the father of Y.
- If W is the mother of Y, then W is the wife of R.
- Therefore, option c) can be true.

d) W is the wife of P:
- The given information states that Y is a legitimate child of W, which means that W is either the mother or the father of Y.
- If W is the mother of Y, then W is the wife of R, not P.
- Therefore, option d) is necessarily false.

Conclusion:
The statement "W is the wife of P" (option d) is necessarily false.

Using the above symbols we get the following family tree:
From the tree diagram, we can see that R and W are the parents of Y as Y is a legitimate child of W.
Therefore it is possible that R is the father of Y and W is the wife of R. Hence the statements in options 2 and 3 are not necessarily false.
Also, from the tree diagram, we can conclude that M and N are the grandparents of Y and hence the statement in option 1 is not necessarily false.
As Y is a legitimate child of W, W is the spouse of R and not P.
Hence the statement 'W is the wife of P' is necessarily false.
