Survey conducted among specific age group: Vicente's survey was conducted among a specific age group within New Mexico, which is residents ages $18$ to $24$ . To determine which population the results are most representative of, we need to consider the demographic that was actually surveyed.
Not limited to specific city: The survey was not limited to a specific city within New Mexico, so it does not exclusively represent Albuquerque residents. Therefore, options $(B)$ and $(D)$ can be eliminated.
Not representative of all New Mexico residents: Since the survey was conducted on New Mexico residents within a specific age range ( $18$ to $24$ ), it is not representative of all New Mexico residents, which includes all age groups. Therefore, option ( $A$ ) is not the correct answer.
Results representative of surveyed population: The survey results are most representative of the population that was actually surveyed, which is New Mexico residents ages $18$ to $24$ . This is because the sample was specifically drawn from this demographic.
