Solution

The correct option is B fusible (easily melted) slag
Smelting - The process of extraction of metal in its molten state by any reducing agent in presence of flux is called smelting.
For example : oxides of less electro - positive metals like Pb, Zn, Fe, Cu are reduced by any other reducing agents.
Here X is -
$F e O + S i O_{2} \to F e S i O_{3}$ fusible slag.
