?In which of the following scenarios would you recommend using associative arrays
 
 
.A. when you want to retrieve an entire row from a table and perform calculations
 
.B. when you know the number of elements in advance and the elements are usually accessed sequentially
 
.C. when you want to create a separate lookup table with multiple entries for each row of the main table, and access it through join queries
 
.D. When you want to create a relatively small lookup table, where the collection can be constructed on memory each time a subprogram is invoked
