The anterior posterior compartment of each segment of drosophila is defined by wingless and engrailed genes. The following statements are given towards explaining their regulation:
A.cells secreting Hedgehog protein activate wingless expression in their neighbors, and the Wingless protein signal, which is received by the cells that secreted Hedgehog, serves to maintain hedgehog (hh) expression.
B.Engrailed protein also acts in an autocrine fashion, maintaining its own expression.
C.The cells expressing engrailed can bind wingless protein because they contain Frizzled, which is the Drosophila membrane receptor protein for Wingless.
D.Binding of Wingless to Frizzled activates the hedgehog signal transduction pathway, resulting in the continued expression of engrailed.
Which of the following option has all the incorrect statements?
