The correct answer is: B. the ordinary members.
The rank and file of the government refers to the ordinary members of the government, such as civil servants and other non-elected officials. These are the people who are responsible for carrying out the day-to-day operations of the government, and they are typically not involved in making policy decisions.
In the context of the question, the statement “There was no opposition to the new policy by the rank and file of the Government” means that the ordinary members of the government did not object to the new policy. This could be because they agreed with the policy, or because they felt that it was not their place to object.
The other options are incorrect because they do not refer to the ordinary members of the government. Option A, the official machinery, refers to the government’s bureaucracy. Option C, the majority, refers to the majority of the members
of the government, which could be either the elected officials or the ordinary members. Option D, the cabinet ministers, refers to the government’s senior ministers.
