Most database systems use indexes built on some form of a B+ tree due to its many advantages, in particular its support for range queries. Leaf nodes are linked together in B+ trees hence range queries are faster.

Explanation:
B-trees and B+trees are both types of balanced tree data structures that are commonly used for indexing and storing large amounts of data. However, there are some key differences between them.
a) B-trees are for storing data on disk and B+trees are for main memory.
This statement is incorrect. Both B-trees and B+trees can be used for storing data on disk or in main memory. The choice between them depends on the specific requirements of the application.
b) Range queries are faster on B+trees.
This statement is correct. B+trees are optimized for range queries, which involve searching for all values within a specified range. This is because B+trees use a linked list structure to connect leaf nodes, which allows for efficient traversal of the tree in the order of the keys.
c) B-trees are for primary indexes and B+trees are for secondary indexes.
This statement is incorrect. Both B-trees and B+trees can be used for primary and secondary indexes. The choice between them depends on the specific requirements of the application.
d) The height of a B-tree is independent of the number of records.
This statement is correct. B-trees are balanced tree structures, which means that the height of the tree is proportional to the logarithm of the number of records. This allows for efficient search, insertion, and deletion operations, even for very large datasets.
Conclusion:
In conclusion, the correct answer to the question is option 'B' because B+trees are optimized for range queries, which makes them faster than B-trees for this type of operation. However, it is important to note that both B-trees and B+trees can be used for a variety of indexing and storage applications, depending on the specific requirements of the application.
