Final answer:
The correct statement regarding preadolescence is that (4) it signals the development of secondary sex characteristics. This stage occurs around 11 to 12 years of age aligned with the start of puberty, not appearing two years earlier in boys than in girls.
Step-by-step explanation:
The correct statement regarding the prenatal developmental stage is that it signals the development of secondary sex characteristics. This stage typically occurs around 11 to 12 years of age and is characterized by the onset of puberty, where observable physical changes begin, including the development of secondary sex characteristics such as pubic hair and breast development in females, and facial hair and a deepened voice in males.
The assertion that preadolescence appears two years earlier in boys than in girls is incorrect, as preadolescence and the onset of puberty generally happen earlier in girls. Intimate feelings are usually not only confided in parents during this stage, as preadolescents start to form their own social circles and may confide in friends. Interest in the opposite sex can be a factor for this group, as they may begin to experience 'puppy love' and develop a sense of identity.
