The correct answer is: D. Neither I nor II is strong
Argument I is not strong because it is based on the assumption that politicians are bad and need to be taught a lesson. This is an unsupported assumption, and there is no evidence to suggest that banning political parties would actually improve the situation.
Argument II is not strong because it is based on the assumption that democracy requires political parties. This is also an unsupported assumption, and there are many examples of democracies that do not have political parties.
In conclusion, neither argument is strong enough to support the conclusion that political parties should be banned.
