How does combat proceed if there is a creature with first strike attacking along with a creature without any abilities?

In a combat situation involving a creature with first strike and a creature without any abilities, the combat damage is processed in two distinct steps due to the presence of the first strike ability.

First strike means that the creature will deal damage to its blockers or to the defending player before any other creatures without that ability can deal damage. In this scenario, the creature with first strike will assign and deal its damage first. After the first strike damage step is completed, the creature without any abilities, which does not have first strike, will then assign and deal its damage.

This two-step process is crucial in understanding how damage is resolved in combat. In a situation where the first striker could potentially destroy or weaken the non-first striking creature before it has the chance to deal damage, the sequence of damage assignment becomes even more critical. Therefore, the correct understanding is that the first striker resolves its damage first, followed by the non-first strike creature, confirming that the sequence follows option C.
