@sergei-rodionov , тут нужно сочетание флагов или аттрибут аффинити в манифесте. Парный флажок - FLAG_ACTIVITY_MULTIPLE_TASK, чтобы отключить проверки и безусловно открывать активити в новой задаче.
Вот запуск без этого флага - в истории один стек:
А вот с этим флажком - стека два:
| setContentView(R.layout.activity_c) | ||
| findViewById<Button?>(R.id.buttonC_openA).setOnClickListener{ | ||
| val intent = Intent(this, ActivityA::class.java) | ||
| intent.flags = Intent.FLAG_ACTIVITY_CLEAR_TASK or |

Мне кажется, тут можно без флажков. Параметр манифеста у активити А singleTask сделает свое дело.
| Intent.FLAG_ACTIVITY_CLEAR_TOP | ||
| startActivity(intent) | ||
| finish() | ||

Тут можно использовать метод finishAffinity. Работает с 16го АПИ
| <activity | ||
| android:name=".ActivityD" | ||

В принципе, можно использовать и стандартный режим. Вы правильно расставили флажки при запуске.
