Answer 1

The correct option is D 1-c, 2-b, 3-a

$\bullet$ Cholera is a bacterial disease caused by $Vibrio$ $cholerae$. It enters our bodies through contaminated water or food. It infects the cells of the intestine and releases a toxin. The toxin causes the body to secrete excess water and salts and showcase the prominant symptoms like diarrhea, fatigue, low bp, etc.

$\bullet$ Pnemonia is a bacterial disease caused by $Streptococcus$ $pneumoniae$. It affects the lung tissue and causes inflammation. As a result of this, the patients face difficulty in breathing.

$\bullet$ Tetanus is caused by exposure of person's wound or cut to the spores of bacterium called $Clostridium$ $tetani$ that might be present in the soil. Spores produce a toxin in the bloodstream that affects the nervous system causing overactivity of brain leading to symptoms like seizures, cramping, etc.
