Answer 1

The correct option is C C $\to$ D $\to$ A $\to$ B

Fever is a defense mechanism. When pathogens enter our body, they produce toxins which are harmful to us. Production of these toxins trigger the white blood cells. These white blood cells produces chemical substances which raises our body temperature. This rise in temperature decreases the multiplication of the pathogens and initiates the process of killing these pathogens.
