According to a theorem, 
"Sum of two sides of a triangle is always greater than its third side." 

Sum of the sides given:9x-6 
So, option D is clearly ruled out. 

Also, option A is ruled out as 3x+2x-4=5x-4<9x-6(for x>1/2). 

Option C is also ruled out as 5x+2+2x-4=7x-2. 

Therefore, option B is correct.
