b."print(sophia.get_num_managed())".The correct option for calling a method to retrieve and print the number of managed employees for the object named sophia is
Step-by-step explanation:
To call a method that keeps track of the number of employees managed by a manager and print this result for an object named sophia, the correct code would be:
print(sophia.get_num_managed())
This code segment assumes that 'get_num_managed' is a method defined within sophia's class. The method name is connected to the object sophia by using a dot (.), and parentheses are used to call the method. It's important to note the correct syntax for method calls in object-oriented programming within Python, or similar programming languages, involve the object name followed by the method name with enclosed parentheses.
