Official Correct Choice:
Option D: Reducing agent
Concept:

In their elemental states, transition metals tend to lose electrons to form positive ions (cations), making them effective reducing agents.

Solution:

  • Vanadium (V) is a metal. Metals generally have relatively low ionization energies compared to non-metals.


  • Because it readily loses electrons to reach stable positive oxidation states (like +2, +3, +4, +5), it causes other substances to be reduced.


  • A substance that reduces another while undergoing oxidation itself is termed a reducing agent.


Why other options are incorrect:

  • While Vanadium(V) oxide (\(V_2O_5\)) can act as an oxidizing agent, the elemental metal itself is fundamentally a reducing agent.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
