The correct option is
D All of the above
Symptoms of cholera can begin as soon as a few hours or as long as five days after infection. Often, symptoms are mild. But sometimes they are very serious. About one in 20 people infected have severe watery diarrhoea accompanied by vomiting, which can quickly lead to dehydration. Although many infected people may have minimal or no symptoms, they can still contribute to spread of the infection. Signs and symptoms of dehydration include:Loss of skin elasticity (the ability to return to original position quickly if pinched).
Rapid heart rate and Low blood pressure.
Dry mucous membranes, including the inside of the mouth, throat, nose, and eyelids.Thirst and muscle cramps, etc.
If not treated, dehydration can lead to shock and death in a matter of hours.
So, the correct answer is 'All of the above'.
