When all the segments differentiate in the embryo, the development is:
Show Hint
Anamorphic development involves sequential addition of body segments and is common in many arthropods.

- Pseudo
- Anamorphic
- Epimorphic
- Complete

The Correct Option is B
Approach Solution - 1
Anamorphic development: segments are added sequentially after the embryonic stage.
Epimorphic development: all segments develop simultaneously during embryogenesis (not the correct answer here).
Pseudo and complete are not standard developmental terms.

Approach Solution -2
Alternate approach - contrast the timing of segment addition:
In anamorphic development, an organism hatches with an incomplete segment count and new segments are progressively added at each successive moult after leaving the embryo - segmentation is not finished inside the egg.
"Pseudo" and "Complete" are not recognised technical terms for arthropod segmentation patterns and can be discarded as distractors.
That leaves the pattern where every body segment is already laid down and differentiated while the organism is still an embryo, with no segments added later - the defining feature of epimorphic development, matching the scenario described in the question.
