Verified by Experts
The correct answer is:
C

In many extraction processes, an oxide is added deliberately to combine with other impurities and form a stable molten phase immiscible with molten metal called a slag. The principle of slag formation is essentially the following.

Nonmetal oxide (acidic oxide) + Metal oxide (basic oxide) ⎯→ Fusible (easily melted) slag.
