Question

how is a mineral of volcanic origin with large crystals most likely formed?
crystallization through evaporation of water
crystallization of molten material inside earth
crystallization of molten material at earths surface
crystallization through cooling of a hot water solution

Explanation:

Large crystals form when molten rock (magma) cools slowly, which happens deep inside Earth where heat dissipates gradually. Surface cooling is fast, forming small crystals; evaporation and hot water solutions form non-volcanic or smaller crystalline minerals.

Answer:

crystallization of molten material inside Earth
