(A) Zn does not react with oxygen directly at room temperature. It forms a protective layer of zinc oxide (ZnO) on its surface, which prevents further reaction with oxygen. This process is known as passivation.
(B) Ti (titanium) also does not react with oxygen at room temperature due to the formation of a protective oxide layer (titanium dioxide, TiO2) on its surface.
(C) Pt (platinum) does not react with oxygen at room temperature either, as it is a noble metal and is highly resistant to corrosion and oxidation.
(D) Fe (iron) does react with oxygen directly to form iron oxide (rust) when exposed to air and moisture.
So, the correct answer is (D) Fe.
