Which of the following statements is/are true? P: The size of a linked list can grow and shrink dynamically during runtime based on the operations performed. Q: Unlike arrays, linked lists allow for constant-time access to elements by index. R: The dynamic nature of linked lists means that memory for nodes is allocated only when necessary, leading to better space utilisation.

Correct answer: (C) Only P and R

Explanation

P is true (lists grow and shrink at run time) and R is true (nodes are allocated only when needed). Q is false: linked lists need O(n) traversal to reach an index; arrays give constant-time indexed access.
