If the X position is 3.5, the Z position is -0.3 and the Y position is 2, the Cartesian coordinates should be written as:

• A. (3.5, 2, -0.3)
• B. (-0.3, 2, 3.5)
• C. (3.5, -0.3, 2)
• D. (2, 3.5, -0.3)

Answer: (A)

The standard 3D Cartesian order is (x, y, z). With X = 3.5, Y = 2, and Z = -0.3, you place them in that order to get (3.5, 2, -0.3). The other formats shuffle the axes, which doesn’t match the given positions, so they’re not correct.
