Five persons A, B, C, D & E are pulling a cart of mass 100kg on a smooth surface and cart is moving with acceleration `3m//s^2` in east direction. When person A' stops pulling, it moves with acceleration `1m//s^2`in the west direction. When person 'B' stops pulling, it moves with accele-ration `24m//s^2` in the north direction. The magnitude of acceleration of the cart when only A & B pull the cart keeping their directions same as the old direction is

A

`26 m//s^2`

B

`2sqrt71 m//s^2`

C

`25 m//s^2`

D

`30 m//s^2`
