Final answer:
The signs that indicate physical neglect are being underweight due to malnutrition and having an unkempt appearance due to poor personal hygiene, making 'Underweight, unkempt appearance' the correct answer.
Step-by-step explanation:
The two things that can indicate physical neglect are being underweight and having an unkempt appearance. This combination suggests a lack of proper nutrition and personal hygiene, which are essential aspects of care. Being underweight is often a result of malnutrition, which can occur due to insufficient calorie and nutrient intake. An unkempt appearance, which includes factors like a messy appearance, can signify a neglect in personal hygiene habits, potentially as a result of a lack of resources, supervision, or awareness. Therefore, the correct answer to the question is 'B) Underweight, unkempt appearance.'
