Here we go ~
As we can see in the figure, lines m and n are parallel to each other. so we can apply Angle pair properties ~
So,

[ they form corresponding angle pair ]
and it's given that :

therefore, by using above information. we can conclude that :

This can be solved by Newton's binomial formula
Tk+1 = (n k) a∧(n-k) b∧k k+1=7 => k=6, n=11 , a=-3x and b=-2y
T7= (11 6) (-3x)∧(11-6) (-2y)∧6 = (11*10*9*8*7)/(1*2*3*4*5) (-3x)∧5 (-2y)∧6
T7= 462 (-3x)∧5 (-2y)∧6
The correct answer is A.
Good luck!!!
