Answer:
Option-4
Explanation:
Cow milk allergy or the cow milk protein allergy occurs when the allergy is caused by the proteins of the cow' milk when provided to the infant baby during the first 6 months.
The allergy is caused when the immune system of the infants consider the proteins of the cow milk as a foreign substance or antigens. These antigens activate the immune response which releases the chemicals and infant develop the symptoms of allergy.

In human populations, ethnic hatred and civil war can cause two populations to become reproductively isolated as happened in Rwanda where the Tutsi and Huttus blamed each other for the problems of their nation and with the result of no friendly relation between the two and a resulting genocide.
Answer: 26.75 meters.
2πr = 84
2 * 3.14 * radius = 84
radius = 84/6.28
r= 13.375
So the diameter will be 13.375 + 13.375 which is 26.75 meters.
