Solution
The correct option is D All of the above
The sense organ of Ascaris is simple elevations supplied by the nerve. They include various papillae, aphids and phasmids. The dorsal lip bears two-minute double papillae whereas single papillae are called as amphid. The amphids are probably chemoreceptors, while the other sensory papillae are perhaps tango receptors. Phasmids are chemoreceptors that open one on either side of the tail of female. So, the correct answer is 'All of the above'
