The correct answer is: B. Only argument II is strong
Argument I is weak because it is based on the assumption that employees have the right to travel free. However, this assumption is not necessarily true. There is no law or regulation that states that employees have the right to free travel. In fact, many companies do not provide free travel to their employees.
Argument II is strong because it is based on the assumption that stopping the issuance of free passes will help the railways to provide better facilities. This assumption is more likely to be true than the assumption in Argument I. If the railways do not have to provide free travel to their employees, they will have more money to spend on other things, such as improving their facilities.
Therefore, only Argument II is a strong argument.
