Expert Solution

Explanation

1) Linked List can be defined as collection of objects called nodes that are randomly stored in the memory

2) A node contains two fields

data stored at that particular address
the pointer which contains the address of the next node in the memory.

3) We have a linkedlist with three nodes(Chu, Bethany and Daryl) and we want to insert a node(Brandon) between nodes Bethany and Daryl

In option a) Update the value of box, next in the node with Bethany first
In option b) Assign the value of box, next in the node with Brandon first

4) If we use option a) where next in the node with Bethany is updated first then we loose the address of Daryl. So option a) is incorrect to do first

5) But if we use option b) where next in the node with Brandon is assigned first, it should be assign with address of Darly and then Bethany next is updated to address Brandon. This completes the insertion operation. and we dont loose any node address. So option b) is correct to do first.
