Show answer and explanation

Answer: A. Hot molten rocks deep below the Earth's surface are called magma

Magma = Inside: As long as the hot, melted rock stays trapped underground (in the crust or mantle), it is called magma
Lava = Outside: The moment that same molten rock breaks through the surface (like during a volcanic eruption), we stop calling it magma and start calling it lava
