Answer 2

(2,-5,4)

Explanation:

The point given has

POSITIVE x coordinate

NEGATIVE y coordinate

POSITIVE z coordinate

Another point that is POS/NEG/POS (x,y,z) will be in the same octant as the point given. When we look at the choices, the one that satisfies this condition is the point (2,-5,4). The x coordinate is POSITIVE, the y-coordinate is NEGATIVE, and z-coordinate is POSITIVE.

This is the correct choice.
