A few things to note when posting questions:
- please use the spoiler function to hide the correct answer. This will allow others to attempt the question without seeing the final answer.
- List the answer choices as A, B, C, etc. (1>5 is confusing)


Okay, onto the solution.
It might be easiest to just 12 list the values in set K.
We get: -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7
We want the range of the positive values.
The positive values range from 1 to 7, so the range is 6.

Answer: B

Cheers,
Brent
