The antigen's foreignness is the most important determinant of immunogenicity when considering an antigen.
An antigen in immunology is a molecule, molecular structure, foreign particle, pollen grain, etc. that may attach to a particular antibody or T-cell receptor. Antigens within the body may cause an immunological response.
Antigens are outside elements. Normally, the body's defence cells don't react to molecules that belong to it (self antigen). A substance's antigenicity is often correlated with its foreignness . When compared to antigen from other members of the same species, it is less antigenic.
A foreign substance must make up the immunogen. Only substances that are not normally found in the body or exposed to the cells of the particular immune system trigger immune reactions. The immune system will distinguish between "self" and "non-self" in normal circumstances.

The correct answer is letter B
Episodic memory is divided into anterograde and retrograde. Anterograde memory consists of our ability to consolidate new memories from a point, while the retrograde consists of remembering experiences that happened earlier in our life. To illustrate the whole process of declarative memory, let us return to the situation of the vacation trip. Telling a friend about the trip to a certain place is a good example of the use of semantic memory, but the episodic fits in this example when you want to tell, for example, how the trip was on the first days of vacation.
Let's say it was raining, which made it impossible to go to the beach as planned. Then, through semantic memory, what happened is expressed, but episodic allows us to evoke what happened at a given time and place of the trip. Still in this example of the trip, the retrograde memory would enter as the capacity to evoke facts that had occurred previously. For example, a friend's suggestion when recommending taking the trip at a certain time of the year or visiting a specific place. While the antegrade would be all over again during the trip, which would now be considered past time, since it is being told to someone.
1. a place to stay
2. dehydration
3. starvation
4. carrying there baggage (if carrying any)
5. if anyone needs medical attention, where they would find it
6. getting a job to make money
extra- if they had to leave anyone behind they would be worried about them or if they had to go different ways!
