Answer:
The correct option is A,. Jenny’s sample was unbiased because she surveyed all households on her block.
Step-by-step explanation:
One critical point in Jenny's research is that her chosen sample was unbiased based on the fact that she chose all households on her block.
The option B does not support the unbiased nature of Jenny's sample but rather supported the validity of the outcome that it would be safe to say that more than 35% of all US households owned three or more cars since her outcome revealed 65% of her chosen population.
