The set of all even whole numbers greater than 4 and less than 12 can be written as:
A= {5,6,7,8,9,10,11}
B= {4,6,8,10,12}
C= {6,8,10,12
D= {6,8,10}
Would it be A ?

Answer 10

just looking for even numbers, impossible to A
it is D

Answer 11

i cant see it, the figure not sense. too small for me :)
