उत्तर

Both (A) and (R) are true and (R) is the correct explanation of (А).

Explanation:

Sponge iron is called Direct Reduced Iron because it is produced by reducing iron ore directly in its solid state using carbon or reducing gases. The removal of chemically bound oxygen creates micropores throughout the ore, leaving behind a porous, sponge-like structure.
