Explanation:

To solve this, we analyze each option:

• Option a: Oxidation reactions involve electron transfer (oxidation - loss of electrons), not replacement.
• Option b: Reduction reactions involve gain of electrons, not replacement.
• Option c: Decomposition reactions break a compound into simpler substances, e.g., \(AB

ightarrow A + B\), not replacement.

• Option d: Displacement reactions (e.g., \(A + BC

ightarrow AC + B\)) involve one element replacing another in a compound, which is also called a replacement reaction.

Answer:

d. Displacement
