Answer: d) G and O
Step-by-step explanation:
In the given picture , we have a number line .
To find : The two points that are 4 units from point K.
When we consider the given number line , we can easily observe that
Point J and L are 1 units from K.
Point I and M are 2 units from K.
Point H and N are 3 units from K.
Point G and O are 4 units from K.
Alternative way :
Distance between any two points on a number line:

The distance of point G from point K:-

The distance of point O from point K:-

Hence, the two points or 4 units from K = G and O
