单项选择题

In many Western European nations, the law is seen as rigid and not open to interpretation. This rigidity grants a consistency to questions of law that many would argue is absent in other, more flexible systems. The European construction of law provides litigants with a clear picture of how a case will be decided. All parties involved are certain how judges will rule on issues. It is simple--judges will strictly follow the law. This simple fact, that the law will not change from one situation to another, allows for court systems in Western Europe to process cases efficiently and cuts down on the amount of frivolous lawsuits. It is useless for an individual to attempt a case if he knows in advance that the law is not in his favor. In the passage, the author is primarily concerned with（）

A. arguing for a universal application of Western European legal practices
B. decrying the rigidity and constancy of Western European legal practices
C. describing the potential benefits of Western European legal systems
D. defining the pros and cons of various legal systems
E. denouncing European law for its anti-consumer bias
