A cup of liquid water at 0°C.
Reason: at the same temperature liquid water contains more internal (thermal) energy than ice because it includes the latent heat of fusion (the extra energy needed to melt ice). A metal spoon at 0°C typically has much less thermal energy because metals have lower specific heat (and the spoon has much less mass than the cup of water). (If masses or materials were different enough, total thermal energy could change, but for the usual comparison the liquid water has the greatest.)
