Explanation : Linear search has linear-time complexity; binary search has log-time complexity.
Here is a table that provides some intuition about the running speeds of algorithms
Logarithmic: Linear:
array size | N
--------------------------------------------------------
8 | 8
128 | 128
256 | 256
1000 | 1000
100,000 | 100,000 ....
Binary search and other divide-and-conquer algorithms have logN time complexity; we say O(logN)
Linear search has linear time complexity: O(N). So the option is 'B'
