A)one maternal protein and three gap proteins.
B)one paternal protein and three gap proteins.
C)one pair-rule,one segment-polarity,and two gap proteins.
D)two pair-rule and two gap proteins.
E)all maternal proteins.

Question

The formation of stripe 2 in a Drosophila embryo involves the interaction of one maternal protein and three gap proteins with the eve stripe 2 enhancer. This combination of transcription factors is crucial for the precise spatial expression of the even-skipped (eve) gene, which is essential for proper segmentation during Drosophila embryogenesis.
