The following is pseudocode for which algorithm?Repeat, starting at the first element:If the first element is what you’re looking for (the target), stop.Otherwise, move to the next element.
A
linear
B
binary
C
bubble
D
merge
Explanation: 

Detailed explanation-1: -Linear search is a sequential searching algorithm where we start from one end and check every element of the list until the desired element is found. It is the simplest searching algorithm.

Detailed explanation-2: -Best Case Complexity-In Linear search, best case occurs when the element we are finding is at the first position of the array. The best-case time complexity of linear search is O(1). Average Case Complexity-The average case time complexity of linear search is O(n).

Detailed explanation-3: -Binary Search is used for searching an element in a sorted array. It is a fast search algorithm with run-time complexity of O(log n). Binary search works on the principle of divide and conquer. This searching technique looks for a particular element by comparing the middle most element of the collection.

Detailed explanation-4: -This task can be solved using binary search over max prefix queries with the Segment Tree.
