In Sequential search, in order to find a particular element, each element of the table is searched sequentially until the desired element is not found. So, in case of an unsuccessful search, the element would be searched until the last element and it would be a worst case when number of searches are equal to the size of the table. So, option (A) is correct.

Sequential Search
Sequential search is a basic search algorithm that sequentially checks each element of a list until a match is found or the whole list has been searched. It can be used to search through an unsorted list of items.
Number of comparisons required for an unsuccessful search
When searching for an element in a sequential search, the number of comparisons required for an unsuccessful search is the number of elements in the list. This is because the algorithm must check every element in the list to determine if the element being searched for is present.
Organized, fixed length, symbol table of length L
An organized, fixed length, symbol table of length L is a data structure that is used to store key-value pairs. The key is used to access the value, and the symbol table is organized in such a way that the key-value pairs can be efficiently searched and retrieved.
Answer
The correct answer is option 'A', which is L.
Explanation
When searching for an element in a sequential search, the algorithm must check every element in the list to determine if the element being searched for is present. In an organized, fixed length, symbol table of length L, there are L elements in the list. Therefore, in an unsuccessful search, the algorithm must check all L elements, which requires L comparisons. Hence, option 'A' is the correct answer.
