_____________ is a Self-Balancing binary search tree, where the path from the root to the furthest leaf is no more than twice as long as the path from the root to nearest leaf.

Correct option is C

A Red-Black tree is a type of self-balancing binary search tree that ensures that no path from the root to any leaf is more than twice as long as any other. This property helps maintain balanced height, allowing efficient search, insertion, and deletion operations.
Information Booster:
1. Red-Black Tree Properties:
· It maintains a balance by assigning a color (red or black) to each node and enforcing specific properties to keep the tree balanced.
· This structure helps prevent the tree from becoming skewed, ensuring that operations like search, insert, and delete remain efficient.
2. Applications: Red-Black trees are widely used in data structures requiring quick search operations, such as associative arrays in many libraries.
Additional Knowledge:
Option (a) Expression tree: Incorrect because an expression tree is used to represent expressions.
Option (b) Game tree: Incorrect as game trees represent possible moves in games.
Option (d) Threaded tree: Incorrect since threaded trees are used for efficient traversal.
