The slope-intercept formula for a straight line is y = mx + b
m and b are constant real numbers
m is the slope of the line
if m is positive, the line slopes up
if m is negative, the line slopes down
Converting 3x+2y=6 to the slope intercept form you get:
y = -3/2x+3 and therefore the slope is -3/2
a perpendicular line to it will have a slope of 2/3 so:
a.4x-6y=3 is the correct answer
(slope intercept form: y=4x/6 -3/6 = 2/3x-1/2)

Hoping you meant 3x "-" 2y = 6...
When lines are perpendicular, their slopes are negative reciprocals.
Therefore, solve each equation for Y, and see which have negative reciprocals when you find the slope (m) in Y=mX+B.
Other than that, I'll "see" if you can get the answer.

Stop cheating. When you go to college you will cheat there to. It looks to me will be cheating in life. That means you will be replaced with a T1 who knows how to solve without asking. Try C. Thats the answer.

3x=2y=6? It means the point (3,2)
How do you have a line perpendicular to a point?
Moreover, there are infinite lines perpendicular to any given line.
