The correct answer is d. Interstitial impurity.

Here's why:

In a crystal lattice, atoms occupy specific positions. However, sometimes, atoms of a different element can occupy the spaces between these positions. These spaces are known as interstitial sites.

In the case of carbon in FCC-iron, the carbon atoms are smaller than the iron atoms and can fit into the spaces between the iron atoms. This is known as an interstitial impurity because the carbon atoms are not replacing the iron atoms in the lattice (which would be a substitutional impurity), but are instead fitting into the gaps between them.

So, carbon sitting in the octahedral void in FCC-iron is an example of an interstitial impurity.
