Choose the correct answer below.LTE 2.1 4GO A. The first quartile is the lower bound of plausible monthly returns, and the third quartile is the upper bound ofplausible monthly returns. Any monthly returns outside of these bounds are outliers. The second quartilerepresents the most common monthly return.OB. Of the monthly returns, 25% are less than or equal to the first quartile, 50% are less than or equal to thesecond quartile, and 75% are less than or equal to the third quartile.53%OC. The first quartile is one standard deviation below the mean (or average monthly return), the second quartile isthe mean, and the third quartile is one standard deviation above the mean.O D. All monthly returns within one standard deviation of the mean are contained in the first quartile, all monthlyreturns within two standard deviations of the mean are contained in the second quartile, and all monthlyreturns within three standard deviations of the mean are contained in the third quartile.(b) Check the data set for outliers.
