Question

The following code searches a linked structure. What is the missing code?
Probe = head
While probe != None and targetItem != probe.data:
< missing code >
If probe != None:
Print("Target item found!")
Else:
Print("Target item not found!")
A) probe.data = next.data
B) probe.next = targetItem.data
C) probe = probe.next
D) probe.head = probe.next

The missing code should update the probe variable to point to the next node in the linked structure. Therefore, choice C (probe = probe.next) correctly updates the probe variable to the next node in the linked structure. Choices A, B, and D don't update the probe variable correctly.
