Option 2 : Non-leaf nodes have pointers to data records

Properties of B+ trees:

B+ tree is height balance tree.
Non leaf node has pointer to a node (leaf or non-leaf) and not pointer to data record
Key value in each node is in sorted order.
Leaf node has pointer to next leaf node.

Structure of non-leaf(internal) node of B+ tree:

Structure of leaf of B+ tree:

Option 2 is not correct.

In a database system, unique timestamps are assigned to each transaction using Lamport’s logical clock. Let TS(T1) and TS(T2) be the timestamps of transactions T1 and T2 respectively. Besides, T1 holds a lock on the resource R, and T2 has requested a conflicting lock on the same resource R. The following algorithm is used to prevent deadlocks in the database system assuming that a killed transaction is restarted with the same timestamp. If TS(T2) < TS(T1) then T1 is killed else T2 waits. Assume any transaction that is not killed terminates eventually. Which of the following is TRUE about the database system that uses the above algorithm to prevent deadlocks?
