The correct configurations are those that can result in four unpaired electrons in an octahedral field. The given configurations seem to be incorrectly formatted, but assuming they aim to represent electron configurations with varying numbers of d electrons, the correct answer would involve configurations that can have four unpaired electrons after considering the crystal field splitting in an octahedral complex. Typically, d^4 (in a high spin case) and d^6 (in a low spin case) configurations can have four unpaired electrons, which seems to be what options under C are hinting at despite the unconventional notation.
