Let $[ \lambda ]$ be the greatest integer less than or equal to $\lambda$. The set of all values of $\lambda$ for which the system of linear equations $x + y + z = 4,3 x + 2 y + 5 z = 3,9 x + 4 y + ( 28 + [ \lambda ] ) z = [ \lambda ]$ has a solution is:
(1) $R$
(2) $( - \infty , - 9 ) \cup [ - 8 , \infty )$
(3) $( - \infty , - 9 ) \cup ( - 9 , \infty )$
(4) $[ - 9 , - 8 )$
