A body at rest breaks up into 3 parts. If 2 parts having equal masses fly off perpendicularly each after with a velocity of 12 m//s when the velocity of the third part which has 3 times mass of each part is
A. 4sqrt(2)m//s at an angle of 45^(@) from each body
B. 24sqrt(2)m//s at an angle of 135^(@) from each body
C. 6sqrt(2)m//s at 135^(@) from each body
D. 4sqrt(2)m//s at 135^(@) from each body
