Answer 1

Hint: Antibodies are proteins produced by an animal body in response to any foreign particle or microbe such as bacteria, virus entering the body. These help to eliminate them and neutralize to protect the body and keep its functions normally.

Complete answer:
Option -A- In the case of snake bites, the injection which is given to the patients, contains preformed antibodies against the snake venom.
In the case of snakebite, a person should be immediately rushed to the hospital. The affected person should be given an injection that contains preformed antibodies. It is called antivenom, the function of it is this antivenom disables toxins of snake venom. It produces reverse action to the damage caused by a bite of a snake. So an injection is a must. Also during emergency conditions like snake bite body needs to respond quickly to injurious stimuli. So injection with preformed antibodies is given rather than relying on the body to make antibodies. So this statement is correct.
Option -B- The fetus receives some antibodies from their mother through the placenta in pregnancy.
During the last three months of the gestation period, the antibodies from the mother cross the placental barrier. The IgG type of antibodies cross the placenta and give immunity to the infant. This type of immunity provided by the mother is known as a passive type of immunity. This provides immunity to a newborn baby. So this statement is also correct.

Option -C- Colostrum secreted by the mother during the initial days of lactation has abundant antibodies to protect the infant.
The secretion of the mammary glands during the first few weeks after parturition is known as colostrum. It has an abundant amount of antibodies IgA. These provide immunity to an infant or newborn baby with a high concentration of nutrients and antibodies. So this statement is also correct.

Option -D- ATS (Anti-tetanus serum) provides temporary protection in case of injuries after burns.
The bacteria Clostridium tetani, bacteria causing tetanus is fatal and enters through cracked skin, cuts, and burns. So an ATS is given immediately to a person with burns to provide immediate protection against this bacteria to prevent it from entering. So this statement is also correct.

So, the correct answer to this question is the option” D” four as all the above-stated statements are correct.

Note: These all statements are correct as all of these are related to providing immunity to the body. The immunity in a person fights against the invaders and helps in eliminating it.
