I would say A because that sort of shows that a kid can have a gun and go crazy.
Answer:
A) an image of a small boy with a gun in his hand
Explanation:
This option can fit the slide format. It is a moving image which may call the students' attention. If the picture makes an effect on the students, the speaker will exploit this effect to warn them against the use of guns. If these are not controlled, they may fall into the hands of children ; and this situation can cause chaos and death.
