Two particles A and B are placed in gravity free space at `(0, 0, 0) m and (30, 0, 0) m` respectively. Particle A is projected with a velocity `(5hat i + 10 hat j + 5 hat k) ms^-1,` while particle B is projected with a velocity `(10 hat i + 5 hat j + 5 hat k) ms^-1` simultaneously. Then,
A. they will collide at `(10, 20, 10) m`
B. they will collide at `(10, 10, 10) m`
C. they will never collide
D. they will collide at 2 s
