Answer:

The correct choices are:

A. At random

D. Represent the population

Explanation:

  • Random sampling ensures that every member of the population or group has an equal chance of representation.
  • Random sampling eliminates the possibility of response or sample bias which gives a universal sample that uniformly represents all members of the population.

  • Convenience and volunteer based samples both have an increased risk of response bias. These samples will only represent selected individuals instead of the entire population.

This is so because, Vitamin B12 is naturally found only in animal foods such as meat, fish, seafood, poultry, eggs, milk, yogurt and cheese. Since the lacto ovo vegetarians do not feed on meat, fish or seafood, the potential sources of vitamin B-12 for a person who follows a lactoovovegetarian dietary pattern are hard boiled egg and dairy products such as yogurt
