Which of the following statements regarding the nonspecific immune response is true?
A. It is antigen-dependent.
B. It results in immunological memory.
C. It combines physical, chemical, and mechanical factors.
D. It involves a long delay between exposure and maximal response.

A. X= Active, Y= Passive
B. X= Acquired, Y= Inborn
C. X= Inborn, Y= Acquired
D. X = Antibodies, Y= White Blood Cells

A. a specific, general response
B. a specific, targeted response
C. a nonspecific, general response
D. a nonspecific, targeted response
