The question asks for the flag’s background colours.
The coat of arms contains additional colours, including green, red and pale areas. Those details do not change the answer: the two large flag bands are yellow and black.
Article 1 of the state constitution defines the state colours. The Interior Ministry explains the detailed design with reference to the State Emblems Act. You can therefore describe colour, arrangement and emblem separately: two equal bands, yellow above black, coat of arms in the centre.

The other three answers
None of the other combinations gives the required two band colours.
blue-white-red
Blue-white-red is a three-colour combination. It does not describe Sachsen-Anhalt’s yellow and black horizontal bands.
green-white-red
Green-white-red is also incorrect. Green and red in an emblem detail are not the two state colours.
white-red
White-red does not match Article 1 of the state constitution. The required colours are yellow and black.
Colours and emblem play different roles in the image.
The colour pair is enough for this test question. A complete description of the current state flag additionally includes the central state coat of arms. Do not mistakenly learn that the official flag is necessarily without an emblem.
The editorial material pictures are only colour aids. They do not show an authoritative official flag template. Consult the linked state source for the exact design.
Article 1(2) · Constitution of Sachsen-Anhalt ↗Sachsen-Anhalt: yellow above, black below.
Do not count the coat of arms’ colours as additional bands.
