need asap show simplest or even answer only. will give good feedback as usual

Which of the following is correct about blocking? Since the computed F-ratio test statistic is greater than the F critical value. therefore location blocking is effective in reducing experimental error. Since the computed F-ratio test statistic is greater than the F critical value, therefore location blocking is unnecessary. Since the computed F-ratio test statistic is less than the F critical value, therefore location blocking is effective in reducing experimental error. O Since the computed F-ratio test statistic is equal to the F critical value, therefore location blocking is unnecessary.Identify the treatments, blocks, and response variable O treatments are the different herbicides, blocks are the different locations and the response variable is the amount of new growth O treatments are the different herbicides, blocks are the different locations and the response variable is the growth period O treatments are the different herbicides, blocks are the months and the response variable is the amount of new growth O treatments are the different herbicides, blocks are the different locations and the response variable is the size of the appleD Scientists in science at Virginia Tech devised an experiment in which 5 differer chard to determine if there were significant differences in ent herbicides and treatment 5 represents a control.
