Answer:

Option B. For every 5 red pens, there are 15 blue pens.

Step-by-step explanation:

The statement expressed the ratio of the red pens to the total as 1 : 4.

This means that for every red pen in the box, there are 4 blue pens.

So, statement A is correct.

Let's skip B an look at other statements as well:

For C, the ratio will be 15 : 60 which translates to 1 : 4. So C is true.

Let's look at D.

This is an interesting one. The problem defines 18 as blue. So it means that 24 - 18 = 6

6 pens will be blue. Again 6 : 24 gives us 1 : 4. So D is true.

B gives us 5 : 24 which is not true.
