Out of platinum, iron, carbon and silver which would be the LEAST suitable as an electrode in a standard Fe3+/Fe2+ half cell, and why?

Pt usually is the metal of choice for making measurements of this type, because of its inertness AND because of reproducibility in measurements. Which metal is the most likely to "mess up" the concentrations of Fe(III)/Fe(II)?
