If a circle having centre at \( (\alpha, \beta) \), radius \( r \), completely lies with in two lines \( x+y=2 \) and \( x+y=-2 \), then \( \min (|\alpha+\beta+2|,|\alpha+\beta-2|) \) is
(a) greater than \( \sqrt{2} r \)
(b) less than \( \sqrt{2} r \)
(c) greater than \( 2 r \)
(d) less than \( 2 r \)
