Using the diagram of the balloons wall and sweater why does the balloon "stick" to the sweater and wall?

• The negative charge of the balloon is attracted and pulled toward the negative charge on the sweater and wall
• The positive charge of the balloon is attracted to and pulled toward the positive charge on the sweater and wall
• The negative charge of the balloon is attracted to and pulled toward the positive charge of the sweater and the wall
• The neutral charge (positive and negative) of the balloon is attracted and pulled toward the positive charge of the sweater and wall
