Option 1: White -> The passage explicitly states "it was all pure white" and "unbroken white" describing the ice and snow covering the landscape as far as the eye could see.
Option 2: Grey -> The opening line describes "Day had broken cold and grey," referring to the atmosphere and sky conditions.
Option 3: Blue -> Not mentioned in the passage as a dominant color.
Option 4: Green -> Pine forests are mentioned but not as a dominating color of the landscape.
Hence, Option 1 (White) and Option 2 (Grey) -> The landscape itself was dominated by white from the extensive ice and snow cover ("unbroken white" for miles), while the atmospheric conditions and sky were grey. Together, these two colors characterized the entire scene the man observed. -> correct
