Question

black earth.

high crop yields.

mineral deposits.

luxria.

Explanation:

Chernozem (also spelled chernozem) is a type of rich, black soil that is highly fertile and is associated with grassland (steppe) ecosystems. It is known for its high organic matter content and is excellent for agriculture, often related to the term "black earth". "High crop yields" is a result of good soil like chernozem but not a synonym. "Mineral deposits" are not related to the definition of chernozem. "Luxria" is not a term related to chernozem (likely a misspelling or incorrect option). So chernozem is another word for black earth.

Answer:

A. black earth
