Final answer:
The Scholar Soul at Tier 3 provides the benefit of counting as having two additional Scholars on your team and grants 8 gold. There was no change to this effect in the 12/8/21 update.
Step-by-step explanation:
The effect of obtaining a Scholar Soul at Tier 3 in a video game context likely resembles a power-up or game mechanic that offers specific in-game advantages. In the context of what seems to be a game update from 12/8/21, the Scholar Soul still grants 8 gold and counts as having two additional Scholars on your team. Therefore, the correct answer to the student's question would be A) Your team counts as having 2 additional Scholars. Also grants 8 gold. There was no mention of a change in the gold granted or attack damage being a part of this ability, and it appears there was no update that affected the Scholar Soul on 12/8/21.
