Given that `vecA+vecB+vecC=0`, out of three vectors two are equal in magnitude and the magnitude of third vector is `sqrt2` times that of either of two having equal magnitude. Then angle between vectors are given by
A. `30^(@), 60^(@), 90^(@)`
B. `45^(@), 45^(@), 90^(@)`
C. `45^(@),60^(@),90^(@)`
D. `90^(@),135^(@),135^(@)`
