An algorithm which has the smallest time complexity is: B. insertion sort.
What is time complexity?
Time complexity can be defined as a measure of the amount of time that is required by an algorithm to run till its completion of the task with respect to the length of the input.
Basically, the time complexity of an algorithm is defined by f(N) if; for all "N" and all inputs with length "N" the execution of the algorithm takes a maximum of f(n) steps. Therefore, the time complexity of an algorithm is also a measure of the efficiency of an algorithm.
In this scenario, an algorithm which has the smallest time complexity is insertion sort with O(N²).
