Which of these iterative processes is unstable? (Note: ( epsilon_n ) is the error in the nth iteration).

( frac{ epsilon_{n+1}}{ epsilon_n} = 1 )

( frac{ epsilon_{n+1}}{ epsilon_n} = 0.5 )

( frac{ epsilon_{n+1}}{ epsilon_n} = 0.75 )

( frac{ epsilon_{n+1}}{ epsilon_n} = 1.25 )

( frac{ epsilon_{n+1}}{ epsilon_n} = 1 )

Which of these iterative processes is unstable? (Note: ( epsilon_n )

1.	Which of these iterative processes is unstable? (Note: ( epsilon_n ) is the error in the n^th iteration).
A.	( frac{ epsilon_{n+1}}{ epsilon_n} = 0.5 )
B.	( frac{ epsilon_{n+1}}{ epsilon_n} = 0.75 )
C.	( frac{ epsilon_{n+1}}{ epsilon_n} = 1.25 )
