Answer:

A. the BY statement.

Step-by-step explanation:

The BY statement aids the procedure MEANS to develop the tree for the current BY group only, thereby analyze the stats, and clean the tree prior to the start and development of the next BY group.

However, without the BY statement, procedure MEANS develops its AVL tree for both the whole file and all sector estimates crossings established in CLASS.

Hence, in this case, the correct answer is the BY Statement.
