At the start of the declare attackers step, the active player must declare which of their creatures are attacking. This is an essential part of the combat phase in Magic: The Gathering. The process involves selecting creatures that will attack the defending player or planeswalker, which sets the stage for how the rest of the combat will unfold.

The rules specify that this declaration initiates the combat process, allowing for the subsequent steps of declaring blockers and resolving combat damage to occur. It's important to understand that the active player cannot perform any actions other than declaring attackers during this part of the turn, which underscores the significance of this phase in the overall game mechanics.

Other options do not pertain to the specific actions required at this point in the turn. Choosing blockers occurs later in the combat phase, after attackers have been declared. Drawing a card typically happens during the draw step at the beginning of a player's turn, and choosing an opponent is not a part of the combat sequence during the declare attackers step.
