Answer 1

Answer: (A)

The organism will not be able to breathe properly.

Medulla oblongata is a part of hindbrain.. It is a triangular part and is connected to spinal cord. It contains centres which control respiration, cardiovascular reflexes and gastric secretions.

Hence, if there is damage to medulla oblongata then the activities associated with respiration, cardiovascular reflexes and gastric secretions will be affected.

So, the correct answer is 'The organism will not be able to breathe properly.'.
