When embryonic development is completed the blastopore of frog becomes

The correct answer is Cloaca

Explanation:

• During embryonic development in frogs, a structure called the blastopore forms. The blastopore is an opening that connects the archenteron (primitive gut) to the external environment.
• In deuterostomes like frogs, the blastopore develops into the cloaca, which is a common cavity for the intestinal, urinary, and reproductive tracts.

Other Options:

• Mouth: The blastopore does not develop into the mouth in frogs. Instead, the mouth forms separately from the stomodeum during embryonic development.
• Nasal Pore: Nasal openings develop independently to connect the nasal cavity to the external environment.
• Gonopore: Gonopores are specific openings for gamete release in certain organisms, but in frogs, reproductive openings are part of the cloaca.
