    Without having to even compute anything, it's pretty intuitive that the vertex that is furthest from O is B on the opposite corner of the cube. Pick up a Rubik's Cube and stare at it if you aren't convinced.

    Since they only expect one answer, the answer must be B.

    For completeness though. The points that are 1 edge away are 1 cm. The points that are 2 edges away (A, E or C) are √2 cm (or about 1.414 cm) and point B is three edges away and is √3 cm (or about 1.732 cm). It's the only one that is more than 1.5 cm away.

    Answer:

    (B) B

    For cubic figures we use an extension of Pythagoras. 

    OB = sqrt(OD^2 + DC^2 + CB^2)

    OB = sqrt( 1^2 + 1^2 + 1^2) 

    OB = sqrt(3) 

    OB = 1.732... 

    Coords of B are ( 1,1,1)
