I am confused between option A and option B? I dont know which one is correct!

Normal (or average) body temperature of humans is often thought to be 98.6F. Is that number really the average body temperature for adult males, or is the true average different? To explore this, a random sample of 19 adult males is selected and their body temperature recorded. The resulting data is used to produce the Excel output below; use it to answer the questions that follow. MaleTemp Mean 98.45 Standard Deviation 0.48 Sample Size 19 95% Margin of Error 0.23 Test Statistic 1.38 p-value 0. 18 Co N [97.6, 97.96] (97.96, 98.32] (98 32 98.68] (98.68 99.04] (99.04, 99.4]Are the calculations/procedures above valid? Select one: O a. Yes, since the necessary conditions are met. O b. Yes, since we were told that the sample was random. O c. No, since we do not know if the sample was randomly selected. O d. No, because the sample size is too small for the CLT to hold
