The correct option is
B Picture A
Option C
Say:
On our screen, we have two crayons that are measured with the help of paper clips.
Steps:
Let us first see how things are measured using objects like paper clips.
To measure a straight object, like a crayon, we begin by putting the paper clips in a straight line starting from the beginning of the crayon till the end of it.
We make sure that there is no overlapping or no gaps between the paper clips.
They should touch each other end to end and form a chain.
We then count the number of paper clips from beginning to end and measure the length.
Here, in this case, Picture B shows the paper clips placed at a distance which is an incorrect way of measuring.
Whereas, picture A follows all the rules correctly.
Thus, Option C is the correct answer.
