When pyridine is treated with a mixture of nitric and sulfuric acids, the major product obtained is 3-nitropyridine. This is because the nitration occurs at the position adjacent to the nitrogen atom in the pyridine ring, giving the 3-substituted product. The other options listed involve substitution at positions further away from the nitrogen atom, which are less likely to occur under these reaction conditions.
