Answer 1

Correct Answer - Option 4 : The groups cannot be compared due to their heterogeneity.

Army personnel go through immense training every day and they are generally fit and belong to a certain age group while the civilian population is more diverse in terms of age group. It contains old people, sick people, women, children etc. Thus, it is not relevant to compare both groups.

Hence, the groups cannot be compared due to their heterogeneity.
