What occurs when a spell provides +4/+4 to the Gray Ogre after its power was increased by a counter?

The situation described involves a Gray Ogre, which is a creature card with a base power and toughness of 2/2. If a counter that increases its power is already applied, let's say it received a +1/+1 counter, it would then become a 3/3 creature.

When a spell subsequently gives the Gray Ogre +4/+4, the increase in power and toughness is calculated on top of its current stats. With the +4/+4 effect, the Gray Ogre, which is currently a 3/3, would gain an additional 4 power and 4 toughness. So, you add 4 to the current power (which is 3) resulting in 7, and 4 to the current toughness (which is also 3) resulting in 7 as well.

The final stats after both effects are applied would be 7 power and 7 toughness, making it a 7/7 creature. Therefore, the correct answer reflects the final total after applying all enhancements to the Gray Ogre.
