Rationale: In ataxic cerebral palsy, the characteristic features include hypotonia (low muscle tone) and muscle instability. These manifestations contribute to the infant's difficulty in achieving independent sitting. Hypertonia (increased muscle tone) and persistence of primitive reflexes, as mentioned in option B, are more commonly associated with other types of cerebral palsy. Tremors and exaggerated posturing (option C) are not typical features of ataxic CP. Hemiplegia (paralysis of one side of the body) and hypertonia (increased muscle tone) mentioned in option D are more commonly seen in other types of cerebral palsy, such as spastic CP.

Correct Answer: D

Correct Answer: C

Rationale: Grading involves adjusting the difficulty level of an activity to match the child's abilities. Bringing a toy closer for easier reach is an example of grading in therapy, helping the child succeed in reaching and grasping the toy within their current capabilities.
