1874 vs 1875.

Three claims for the “global historical surface temperature anomalies” of the January-to-December calendar years 1874 and 1875 as per HadCrut4 version 4·0·0·0.

1st claim.   The global temperature anomaly of 1874 is between A and B.
2nd claim.  The global temperature anomaly of 1874 is between C and D.
3rd claim.   The global temperature anomaly of 1874 is between E and F.

A = 0·64(±0)ºC more than the global temperature anomaly of 1875.
B = 0·58(±0)ºC less than the global temperature anomaly of 1875.
C = 0·35(±0)ºC more than the global temperature anomaly of 1875.
D = 0·29(±0)ºC less than the global temperature anomaly of 1875.
E = 0·15(±0)ºC more than the global temperature anomaly of 1875.
F = 0·18(±0)ºC less than the global temperature anomaly of 1875.

The monthly series entails the 1st claim. The annual series entails the 2nd claim. The “decadally smoothed” annual series entails the 3rd claim. Which claims are true? Which claims are false? Which claims are neither true nor false?  Alternative link for version 4·0·0·0.
