Answer: The correct option is (C) decimeter.
Step-by-step explanation: Given that a meter stick is divided into 10 equal parts.
We are to select the correct option which is the name of each part of the stick.
The length of the stick = 1 meter.
If we divide the stick into 10 equal parts, then each part is equal to one-tenth of the stick.
That is, each part of the stick is of a meter.
We know that one-tenth of 1 meter is equal to one decimeter, so each part of the stick is equal to one decimeter.
Thus, each part of the stick is called a DECIMETER.
Option (C) is correct.
