The binarySearch() method in the Arrays class is specifically designed to search for a specified key value in an array using the binary search algorithm. This method is more efficient than linear search in larger arrays, as it reduces the search time complexity to O(log n), where n is the size of the array. Therefore, the best choice is A. The other methods - sort(), equals(), and search() - are not specifically designed for searching an array using a key value, and may not be as efficient as binarySearch() for this purpose.
