The correct answer is: Only argument II is strong.
Argument I is weak because it is based on the assumption that there may be certain circumstances that compel officers to take bribes. However, this assumption is not necessarily true. There are many officers who take bribes simply because they want to make more money or because they are corrupt. Even if there are certain circumstances that compel officers to take bribes, this does not mean that they should not be punished. They should still be held accountable for their actions.
Argument II is strong because it is based on the principle that officers should do the job they are entrusted with honestly. This is a principle that is widely accepted and that is essential for the proper functioning of society. If officers are allowed to take bribes, it will undermine public trust in the government and lead to corruption.
Therefore, only argument II is strong.
