Short answer: All of the options can occur, but the most direct/sure single effect is that eruptions can drastically alter the ecosystem.

Details:
- Add nutrients to the surrounding soil — True. Volcanic ash and lava break down into mineral-rich soils that can be very fertile.
- Drastically alter the ecosystem — True. Eruptions can destroy habitats, change landforms, and alter climate locally/regionally.
- Draw animals to the area — True in many cases over time. After initial devastation, recolonization and attraction to new habitats or food sources can occur.
- Increase biodiversity — Possible in the long term. New habitats (e.g., volcanic islands, succession stages) can lead to colonization and speciation, but biodiversity often decreases immediately after an eruption and only increases later.
