1pt If the room is the frame of reference for the study of an object moving in three dimensions, from where should distances be measured? O A. one wall and the floor
OB. two walls and the floor
O c. the floor and the ceiling
O D. the door

Option B, two walls and the floor

Explanation:

The distance should be measured from the point where at least the three axed meet.

Two walls and the floor are equivalent to three axes.

Vertical wall 1 = Y Axis

Horizontal wall2 = X Axis

Floor = Z Axis

Thus, the distance should be measured from the point where two walls and one floor meet.

Option , B is correct
