Since a and b are two consecutive even integers and a > b, then a = b + 2;

Given: 3(b + 2) < 2b;

b < -6.

Since a and b are consecutive even integers and a > b, we can say that a = b + 2.

We can substitute b + 2 for a in the inequality 3a < 2b and we have:

3(b+2) < 2b

3b + 6 < 2b

b < -6

Answer: C
