We can use the groupingBy collector to group employees by their title and then use the counting collector to count the number of employees in each group. The code would look something like this:

Map<String, Long> employeesPerTitle = employeeStream.collect(Collectors.groupingBy(Employee::getTitle, Collectors.counting()));

This will give us a Map where the keys are the titles and the values are the number of employees with that title. Choice A is the only option that has the correct syntax for this code.
