10 month old child can not perform?
**Core Concept**
The question is testing the cognitive and motor development milestones in infants. At 10 months, children are expected to have achieved certain gross and fine motor skills, language development, and problem-solving abilities.
**Why the Correct Answer is Right**
At 10 months, a child is expected to perform certain tasks such as sitting without support, crawling, standing with support, and possibly walking while holding onto furniture. They should also be able to point to body parts when asked, follow simple verbal commands, and understand object permanence. This is a critical period for gross and fine motor development, and any significant delays may indicate a developmental disorder.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it is not a specific developmental milestone. The question is asking for a specific task that a 10-month-old child cannot perform.
**Option B:** This option is incorrect as a child at 10 months is expected to be able to sit without support, which is a major milestone in gross motor development.
**Option C:** This option is incorrect as a child at 10 months is expected to be able to point to body parts when asked, which is a sign of language development and cognitive growth.
**Clinical Pearl / High-Yield Fact**
A significant delay in gross motor development, such as sitting or walking, may indicate a neurological or muscular disorder. It is essential to assess these milestones regularly during well-child visits to detect any potential developmental issues early.
**Correct Answer: B. Sitting without support.**
