Hey!

[tex]\large\boxed{C.~2.5~cm.}[/tex]
-------------------------------------------------
Explanation:
On the centimeter it's measures in increments of 5. The iron passes the 95 mark, so we can automatically take out option A and B. The iron rod looks like its half way between the 100 and 95 mark. So we can say that the possible error of measurement is 2.5cm. 1cm. seems to small.

Hope This Helped! Good Luck!
