Target entity: CIE 2° standard observer
Context triple: [International Commission on Illumination, definesStandard, CIE 2° standard observer]

• A. CIE standard illuminant D65
  CIE standard illuminant D65 is a standardized representation of average daylight with a correlated color temperature of about 6500 K, widely used as a reference white point in colorimetry and imaging systems.
• B. CIE 1931 XYZ
  CIE 1931 XYZ is a foundational color space defined by the CIE that models human color perception using three tristimulus values (X, Y, Z) and underpins much of modern color science and colorimetry.
• C. CIE standard illuminant D50
  CIE standard illuminant D50 is a standardized light source representing average midday daylight with a correlated color temperature of about 5000 K, commonly used as a reference for color-critical applications such as printing and graphic arts.
• D. CIE standard illuminant D75
  CIE standard illuminant D75 is a defined daylight illuminant with a correlated color temperature of about 7500 K, representing cool, overcast daylight conditions for colorimetry and imaging applications.
• E. Ostwald color system
  The Ostwald color system is a color classification and harmony model developed by chemist Wilhelm Ostwald that organizes colors based on their psychological perception and mixture relationships.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
