B)The wall changes shape and the positive charges move to the inside.
This is a static electricity phenomenon.
When an element such as this balloon is rubbed against a comb or a surface,
it induces negative charge leaving the comb or the surface positiveliy charged.
When this negatively charged balloon is moved against a wall,
It repels the electrons of the wall and induces positive charge on it.
Hence, the positive and negative charges attract each other.
And thus a charged balloon can attract a wall.
