The correct answer is B. Either I or II is implicit.
The statement does not provide enough information to determine whether the judges were negligent in discharging their duties or whether there was a charge of misconduct against them. However, it is possible that either of these things could have led to their suspension. The statement also does not provide any information about the government officials, so it is impossible to say whether they were biased against the judges.
Therefore, the only assumptions that can be made based on the statement are that either the judges were negligent in discharging their duties or that there was a charge of misconduct against them.
