The correct answer is: Only argument II is strong.
Argument I is not a strong argument because it does not provide any evidence to support the claim that the practice of transfers of clerical cadre employees from government offices of one city to those of another should be continued. The argument simply states that transfer of employees is a routine administrative matter, but it does not explain why this is a good reason to continue the practice.
Argument II is a strong argument because it provides evidence to support the claim that the practice of transfers of clerical cadre employees from government offices of one city to those of another should be stopped. The argument states that the practice involves a lot of governmental expenditure and inconvenience, and that these costs outweigh the benefits of the practice.
Therefore, the correct answer is: Only argument II is strong.
