Final answer:
The quote that clearly indicates a reference to stage 3 and describes the girls at that stage is 'it was during stage 3 that we met our first purebred girls'.
Step-by-step explanation:
The quote that best represents the girls at stage 3 from the given options is B) "it was during stage 3 that we met our first purebred girls". This quote specifically addresses the stage in question and directly refers to the girls being described at that particular stage. In contrast, the other quotes do not provide a clear indication of the girls' characteristics or situation during stage 3, which is the focal point of the question.
The most suitable quote that represents the girls at stage 3 from the given options is B) "it was during stage 3 that we met our first purebred girls." This quote precisely addresses the stage under consideration and explicitly refers to the girls being described during that specific developmental phase. Unlike the other quotes, which do not provide a clear indication of the girls' characteristics or situation at stage 3, option B directly correlates with the question's focus on the girls' attributes during this particular stage. This choice effectively captures the essence of the girls' introduction and significance during stage 3 in the given context, making it the most appropriate option for representing the described developmental phase.
