Answer is Right!
Answer is Wrong!
The correct answer is: C. Limited.
Infants have a limited ability to produce antibodies because their immune systems are still developing. This means that they are more susceptible to infection than adults. However, infants do have some protection from antibodies that they received from their mothers while they were in the womb. These antibodies provide some protection against certain infections, but they will eventually wear off.
Option A is incorrect because infants do have some ability to produce antibodies, but it is not as strong as an adult’s.
Option B is incorrect because infants do have some ability to produce antibodies.
Option D is incorrect because infants do not have the same ability to produce antibodies as adults.
