Sİmilar meaning

Hello teachers

Main sentence:

Organic food doesn't have any additional nutritional benefits when compared with conventionally produced food, nor is it any safer to eat.

Which sentence has the similar meaning of the main sentence above?

1- Organic food is neither more nutritious nor safer to eat than conventionally produced food.

2- Organic food is not as safe to eat as conventionally produced food and is not as nutritious, either.

3- Conventionally produced food is safer to eat than organic food and contains more nulrients.

4- There is no difference between organic food and conventionally grown food in terms of nutritional value, but the latter is safer to eat.

5- While conventionally produced food and organic food share the same nutritional qualities, it is safer to eat organic food.

I don't understand this exercise. I think all of the sentences above have the same meaning as the main sentence. There must be a mistake. What do you think?
