Haeckel's recapitulation theory/biogenetic law states
From the biogenetic law or embryological parallelism often communicated utilizing Ernst Haeckel's expression "ontogeny restates phylogeny"is an authentic speculation that the advancement of the developing life of a creature, from preparation to incubation or bring forth (ontogeny), experiences stages taking after or speaking to progressive stages in the advancement of the creature's remote precursors (phylogeny).
So, the correct option is 'Ontogeny repeats phylogeny'.
