Which statement best describes the internal structure of a LinkedList<T> in C#?

AIt stores elements in a contiguous memory block like an array

BIt uses a hash table internally for fast lookups

CIt uses nodes containing data and references to next and previous nodes

DIt stores elements as key-value pairs

Step-by-Step Solution

Solution:

Step 1: Recall LinkedList structure
LinkedList is made of nodes, each holding data and links to neighbors.
Step 2: Compare with other data structures
Unlike arrays or hash tables, LinkedList nodes are linked by references, not contiguous.
Final Answer:
It uses nodes containing data and references to next and previous nodes -> Option C
Quick Check:
LinkedList = nodes with data + next/prev refs [OK]

Quick Trick: LinkedList nodes link forward and backward [OK]
