The image on the left shows the charges on a balloon after it’s been rubbed with a wool cloth. The image on the right is a piece of tissue paper. What will happen to the tissue paper as it approaches the balloon and why?

B = tissue paper will stick to the balloon because it is positively charged.

Explanation:

The option B is correct. Balloon is negatively charged while it is stated in question and can also see from the picture tissue paper is positively charged.

We know that opposite charges attract each other. Thus when balloon and tissue paper come close to each other the stick together.

All other options are incorrect because,

Option A:

In option it is stated that tissue paper is negatively charged. Although negative charges are present but there is more positive charge in balloon we can say that more number of protons are present thus balloon have positive charge.

Option C:

Tissue paper is negatively charged and will move away.

It is wrong. Tissue paper is positively charged.

Option D:

Tissue paper will move away because it is  positively charged. It is also wrong statement because tissue paper will not move away it will stick to the balloon because of positive charge.
