• B. Yes. Nothing is wrong.
• C. Both b and c.
• D. No, the pins should be placed alike from start to end.

Answer 1

The correct option is C Both b and c.

Say:
Major Mint is measuring the length of the pencil using paper clips.
Let us see if he is measuring it correctly.

Steps:
To measure a straight object, like a pencil, we begin by putting the paper clips in the straight line starting from the beginning of the pencil till the end of it.
We make sure that there is no overlapping or no distance between the paperclips.
They should touch each other and form a chain.
We then count the number of paper clips from beginning to end and measure the length.
Here, Major Mint has not placed the clips alike. Some are facing ahead while some are facing down.
Also, they are not kept in the same line and are either overlapping or kept up and down.
Hence, he is not measuring it correctly.
With the discussed reasons, options B and C are both correct. Thus, the correct answer is Option D.
