A. may be read, but not written (something more is needed to do so)
Example:
Global variables cannot be written without using global
>> Example 1:
x = 10
def change():
x = x + 1 #UnboundLocalError
>> Example 2:
x = 10
def change():
global x
x = x + 1
change()
print(x) #output 11
x = 5 # Global variable
def my_function():
print(x) # Can read the global variable
# x = 10 # This would create a local variable and would not modify the global variable
my_function() # Prints 5
print(x) # Still prints 5, because we did not modify the global variable inside the function
