Final answer:
Option A: The maximum number of records can be found by summing the number of records at each level and subtracting one for the root node.
Step-by-step explanation:
The maximum number of records that the structure can contain can be calculated by summing the number of records at each level of the tree. At the first level, there is a single node which can contain 2 records. At the second level, there are 2 nodes, each of which can contain 2 records, resulting in a total of 4 records. At the third level, there are 4 nodes, each of which can contain 2 records, resulting in a total of 8 records. Finally, at the last level, there are 8 nodes, each of which can contain 2 records, resulting in a total of 16 records.
To find the maximum number of records, we sum these values: 2 + 4 + 8 + 16 = 30 records. However, we need to subtract the root node which always contains 1 record. So the maximum number of records in this structure is 30 - 1 = 29 records.
Therefore, the correct answer is A) 29.
