The correct option is A Options a, b, and c are correct.
Say:
Jax and Jane are measuring the length of the pencil using paper clips.
Jax says it is 5 paperclips long while Jane says it is 3 paper clips long.
Steps:
Both Jane and Jax are following the rules of measurement, i.e., the clips are not overlapping and are kept in a straight line, touching each other like a chain.
The only difference is that Jax’s clips are smaller than Jane’s clips.
Thus, both of their measurements are correct.
This difference is because of the size of the clips.
So we can say that Jax’s 5 paper clips = Jane’s 3 paper clips.
This makes all the three options, i.e., a, b, and c correct.
Hence, the correct answer is option D.
