Solution
The correct option is B Outgrowth of gut
The stomochord arises as an outgrowth from the outer cells of the embryonic gut whereas notochord is developed from cells from the mesoderm, which is a middle layer of the embryo. Hence, the notochord is not an outgrowth, as it is developed from the dorsal cells inside the embryonic gut. Stomocord helps in locomotion while notochord is supportive in function.
Thus, the correct answer is option B, 'Outgrowth of the gut.'
