Given figures illustrate.

Options

A. `{:(" "P," "Q),("Metamerism by a cnidarian", "Multiple fission by a protist"):}`
B. `{:(" "P," "Q),("Strobilation by a cnidarian", "Multiple fission by a protist"):}`
C. `{:(" "P," "Q),("Fragmentation by a platyhelminth", "Internal budding by a sponge"):}`
D. `{:(" "P," "Q),("Strobilation by a platyelminth", "Sporulation by a protis"):}`

Answer

b

Explanation

Figure 'P' shows strobilation in Aurelia (a coelenterate/cnidarisn). Strobilation refers to repeated formation of similar segements by the process of budding figure 'Q' shows multiple fission in Amoeba (a protozoan protist), during which many daughter nuclei are produced by the repeated divisions of the parent nucleus.
