It is the indirect protection from an infectious disease. It happens ...

Option c is correct.

Option a is incorrect: PLACID Trial includes Convalescent Plasma which is extracted from the blood of patients recovering from an infection. It is a source of antibodies against the infection. The therapy uses blood from people who have recovered from an illness to help others recover.
Option b is incorrect: Flattening the curve is a public health strategy to slow down the spread of the SARS- CoV-2 virus during the COVID-19 pandemic. Flattening the curve means slowing the spread of the epidemic so that the peak number of people requiring care at a time is reduced, and the health care system does not exceed its capacity.
Option c is correct: 'Herd immunity', also known as 'population immunity', is the indirect protection from an infectious disease. It happens when a population is immune either through vaccination or immunity developed through previous infection. WHO supports achieving 'herd immunity' through vaccination, and not by allowing a disease to spread through any segment of the population, as this would result in unnecessary cases and deaths.
Option d is incorrect: RTPCR is a technique to test covid. Reverse transcription polymerase chain reaction (RT-PCR) is a laboratory technique combining reverse transcription of RNA into DNA and amplification of specific DNA targets using polymerase chain reaction (PCR). It is primarily used to measure the amount of a specific RNA.
