(a) 0 rank is impossible, as there are nonzero entries in the matrix. 
(b) 1 rank is impossible, since there are odd number of 1 entries in the matrix, any number of row 
operations we do, they do not cancel each other. 
(c)   [
   
   
   
] 
(d)   [
   
   
   
] 
 
Let us prove that 
                     ( ) 
and 
                          ( ) 
have the same solutions. It follows easily that 
    (   )        ( ) 
It is clear that solutions of (2) are solutions of (1).  
Now suppose x is a solution of (1). 
Then multiply (1) by    to the left,
 (  )  (  )      
We assume here that A is a real matrix and x is a real vector, hence we get Ax = 0. 
 This implies that the solutions of (1) are the solutions of (2).
