Answer:

A) 2 rungs.

Step-by-step explanation:

Let X be the starting point. The new point after climbing 4 rungs is:

[tex]x+4[/tex]

-The new distance after sliding down two rungs is:

[tex]=(x+4)-2\\\\=x+2[/tex]

-The net climb is calculated by subtracting the latter from the prior:

[tex]Net \ climb=(x+4)-(x+2)\\\\=2[/tex]

Hence, the net climb is 2 rungs.
