Correct Answer is A
Explanation
A. By 10 months, an infant should be able to sit steadily without support. This milestone is essential for proper development, and the inability to do so may indicate developmental delays or underlying neurological issues.
B. Building a tower of three or four cubes is a skill typically expected at 18 months, so it is not a concern for a 10-month-old infant.
C. Turning pages in a book is a fine motor skill usually developed around 12-18 months, so it is not expected for a 10-month-old infant.
D. Imitating animal sounds is a language skill that develops around 12-18 months, so it is not expected for a 10-month-old infant.
Correct Answer is B
Explanation
A. Babbling one-syllable sounds is appropriate for a 7-month-old infant and indicates typical language development.
B. Using a unidextrous grasp (using only one hand) could indicate a preference that needs further evaluation. At this age, infants should use both hands equally, and a strong preference for one hand might signal neurological concerns.
C. Fear of strangers is a normal developmental milestone that typically appears around 6-8 months of age.
D. Showing preferences towards foods is typical as infants begin to develop tastes and preferences during the introduction of solid foods.
