How many replicates do you need to be a statistically sound experiment?

The number of replciates will be really dependant on what type of experiments we;re doing, but it should be at least 2 replicates.
Making replicates in an experiment is really useful to make sure that the data that we collected is correct and not misguided, so we could utilize that data and make the most reliable conclusion as possible

In my opinion choice a would be the correct one
