Fgf10 is function as positive feedback factor in different ways such as___

a) to maintain the activation of both Wnt2b and Tbx5

b) to tells the surface ectoderm to continue to make Fgf8, and the surface ectoderm continues to tell the underlying mesoderm to make Fgf10

c) to maintain the activation of both Wnt3a and Tbx4

d) to tell the mesenchyme cells directly beneath it to continue making Fgf10
