Allergic responses to inhaled antigens occur when an individual is first sensitized to the antigen (i.e., the allergen), inducing an immune response and then has a subsequent exposure to the same antigen. The sensitization phase is characterized by <u>Induction of a CD4 T cell type II immune response</u>.
The process by which your body becomes sensitive to a particular substance is called sensitization. When your immune system becomes sensitized to an allergen, you can develop certain symptoms.
Antigens that can induce an allergic response are called allergens, and they are often derived from non-infectious or non-microbial sources.

Explanation:
If there's this picture in the question, the right answer is metaphase.
A metaphase qualifies a phase of meiosis or mitosis (following prophase and preceding anaphase) during which chromosomes, or at least kinetochores, align with the equatorial plate of the spindle. At this stage, chromosomes are at their maximum condensation and karyotypes are usually established. In the first division of meiosis, the metaphase represents the phase during which meiotic analysis is usually accomplished.
Amino acids make up proteins, and proteins are needed for proper growth in humans. They’re essential because, without them we wouldn’t have the nutrients we need to survive. I hope this helped!
