The correct answer is: D. Neither I nor II is strong.
Argument I is not strong because it is based on the assumption that non-vegetarian food is expensive. However, this assumption is not necessarily true. There are many affordable non-vegetarian food options available, and the cost of non-vegetarian food is not necessarily prohibitive for most people.
Argument II is not strong because it is based on the principle that nothing should be banned in a democratic country. However, this principle is not absolute. There are many things that are banned in democratic countries, such as hate speech and child pornography. Therefore, the argument that non-vegetarian food should not be banned simply because it is a democratic country is not persuasive.
In conclusion, neither argument I nor II is strong.
