Random sampling:
A simple random sample of size n is collected from a large population where each and every unit in the population is equally likely to be selected in the sample. It is a method of sampling using a random or the methods of probability, to obtain a representative sample.
The methods of random sampling are true about the statement in option A.
Four tosses of an unbiased coin is an example of random sampling from a Binomial random variable with the probability of success of -0.5 and a sample size of 4.
Option A is correct.
