Describe a disadvantage of a linear search algorithm
A
Data does not need to be in order.
B
Performs well over large ordered lists.
C
Can only work on an ordered list. If unordered must use a linear search.
D
Slow with large data sets.
Explanation: 

Detailed explanation-1: -The drawback of a linear search is the fact that its time consuming for the enormous arrays. Inversely, slow searching of big lists. Every time a vital element matches the last element from the array or an essential element does not match any element Linear search algorithm is the worst case.

Detailed explanation-2: -Linear search’s disadvantage is the time complexity. Because linear search scans each element starting from the beginning, it is highly inefficient. The graph for linear search would model y = n. Meanwhile, binary search finds elements by starting at the midpoint of the data set for each comparison.

Detailed explanation-3: -Advantages of a linear search With today’s powerful computers, small to medium arrays can be searched relatively quickly. The list does not need to sorted. Unlike a binary search, linear searching does not require an ordered list. Not affected by insertions and deletions.

Detailed explanation-4: -Linear search is less efficient when we consider the large data sets. Binary search is more efficient than the linear search in the case of large data sets.
