Concept:
The World Trade Organization (WTO) is an international organization established in 1995 to regulate international trade and ensure that trade flows as smoothly, predictably and freely as possible.
Its objectives include administering trade agreements, providing a forum for trade negotiations, settling trade disputes and cooperating with other international organizations.
Step 1: Examine each option.
• [(A)] Administering multilateral trade agreements is one of the primary objectives of the WTO.
• [(B)] WTO assists developing countries in trade policy implementation and capacity building.
• [(C)] Reduction in inequality of income is not a direct objective of the WTO. Although trade may indirectly influence income distribution, reducing inequality is not one of its stated objectives.
• [(D)] WTO cooperates with organizations such as the IMF and the World Bank to promote coherence in global economic policy.
Therefore,
\[
\boxed{\text{Reduction in inequality of income is not an objective of the WTO.}}
\]
Hence, the correct answer is
\[
\boxed{(C)\;\text{Reduction in inequality of income}}
\]
