@sindhiyadevit Thank you for your valuable response.Please refer the correct answers.

• b) A linked list is a collection of elements with a linear data structure, where each element points to the next element in the list through a pointer or reference.
• c) Use the unshift() method to add a new element to the beginning of a linked list.
• a) Use the push() method to add a new element to the end of a linked list.
• b) The time complexity of accessing an element in a linked list is O(1), since it only requires traversing through one node to access the desired element.
• b) Use the shift() method to remove an element from the beginning of a linked list.
