no they are actually similar answers.
a)b) ans: eyes are considered to be the most important organ of human body. these were initially found as photosensitive eye spots in planaria. later due yo evolution the structure began to change but still the function was the same. be it eyes of octopus, insects, vertebrate or planaria, the function of the eye is the same but the morphological structure is different. so these animals can be classified under animals having analogous organs.
