Rationale: In Freud's psychosexual development theory, the oral stage is the first stage and occurs during infancy. It focuses on activities involving the mouth, such as sucking and feeding. This stage is crucial for the child's development as it forms the basis for trust and attachment. Choices B, C, and D are incorrect as latency refers to the stage during middle childhood where sexual impulses are suppressed, genitality refers to the final stage focusing on mature sexual relationships, and anality refers to the stage occurring during the toddler years where toilet training plays a significant role.

Rationale: The correct answer is C: 'The condition is incompatible with life.' Anencephaly is the most serious neural tube defect where both hemispheres of the brain are absent. It is incompatible with life, as there are no medical or surgical treatment options available. While some infants with mature brain stem function can maintain vital functions for a short period, anencephaly is ultimately not survivable. Choice A is incorrect as there are no treatment options for anencephaly. Choice B is incorrect as immediate surgery is not necessary for this condition. Choice D is incorrect as an infant with anencephaly will not have permanent disabilities since the condition is not compatible with life.

Choice D is incorrect because iron is best absorbed on an empty stomach.
