My answer will be D, 11
-4 is the least integer in the list K, and K consists of 12 consecutive integers. Range=Large- small integer, range=7-(-4)=11
(-4,-3,-2,-1,0,1,2,3,4,5,6,7)--->12 consecutive integers that list in K. :)

Official Answer is B, 6.

this is correct.

the positive integers in the list are 1, 2, 3, 4, 5, 6, and 7, so the range is biggest - smallest = 7 - 1 = 6.

lesson one:
READ PROBLEMS CAREFULLY.
don't miss words like 'positive'. this is not a hard problem, but it's easy to miss if you are inattentive.

lesson two:
KNOW YOUR TERMINOLOGY / CLASSIFICATIONS.
zero is not a positive number.
