A) Default arguments can be provided by supplying them in the function header. For example, a function may be defined as follows:
```
def my_function(arg1, arg2=10, arg3="Default"):
    # code here
```
In this case, `arg2` and `arg3` have default values of 10 and "Default", respectively, but can be overwritten by providing new values when calling the function.

D) Default arguments can also be provided by assigning values to the keys in the function header. For example:
```
def my_function(arg1, arg2=None, arg3=None):
    arg2 = arg2 or 10
    arg3 = arg3 or "Default"
    # code here
```
In this case, the variables `arg2` and `arg3` are set to `None` by default, but are reassigned to 10 and "Default", respectively, if the user does not provide any values for them.
