Same link mentioned above says that it is possible to delete, but after creating a subnet it is not possible. So the answer is D.

Prerequisite: To delete a security list, it must not be associated with a subnet yet. You can&#39;t delete the default security list in a cloud network.

We can surely add or remove security lists after subnet creation so, option D is incorrect.
Option C is also incorrect as individual end points or instances don&#39;t require a security list. All endpoints and instances within a subnet are governed by security list(s) associated with that subnet.
Even option A &amp; B are incorrect.

If Option C - &quot;Each network endpoint or instance in the subnet needs its own security list&quot; is modified slightly for eg - &quot;Each network endpoint or instance&#39;s traffic in the subnet is governed by security list.&quot; then it could be the right option

D is not correct.

To change which security lists a subnet uses:
- To remove a security list: Click the X next to the security list.
