The correct answer is: A. Only assumption I is implicit
The statement “Money is the root cause of all the problems in a family” does not necessarily mean that there are always some problems in a family. It is possible that a family could be perfectly happy and content without any money at all. However, the statement does imply that every problem is caused by something. If money is the root cause of all the problems in a family, then it follows that every problem must have a cause.
Assumption I is implicit in the statement because the statement implies that every problem has a cause. Assumption II is not implicit in the statement because the statement does not say anything about whether or not there are always some problems in a family.
