Given below are two statements.

Statement I: When ready-made antibodies are directly given to protect the body against foreign agents, it is called passive immunity.

Statement II: Passive immunity is slow and takes time to give its full effective response. 

In light of the above statements, choose the most appropriate answer from the options given below.

Statement I is correct. Passive immunity indeed refers to the transfer of ready-made antibodies from one individual to another to provide immediate protection against an antigen. This can happen through maternal antibodies passed to a baby via the placenta or breast milk, or through injections of antibodies.
Statement II is incorrect. Active immunity is slow and takes time to give its full effective response. Passive immunity typically offers immediate protection since the pre-formed antibodies can quickly neutralise the antigen.
