They are asking which is the worst. There are many flaws with this, I will point out two.
1. The question "which is the superlative" can't be compared that way, each answer is independent of the every other answer.
The 50% who thought Mariuana was the worst, would probably also say drinking was more dangerous, too.
2. That is a website for parents looking up information on game violence.
I would cite regulation, but I know you will simply ignore it.
