10 month old child can not do –a) Change cube from one hand to anotherb) Can build a cube of sixc) Can pull and standd) Can talk a sentence of 4 to 5 wordse) Pincer grasp

**Core Concept**
The question assesses the developmental milestones of a 10-month-old child, focusing on **fine motor skills**, **gross motor skills**, and **language development**. At this age, children typically demonstrate specific abilities that are crucial for their overall development.

**Why the Correct Answer is Right**
A 10-month-old child is expected to have certain skills such as **transferring objects** from one hand to another, **pulling themselves to a standing position**, and starting to use **simple gestures** or sounds to communicate. However, more complex skills like **building a tower of cubes** or **using pincer grasp** to pick up small objects usually develop a bit later.

**Why Each Wrong Option is Incorrect**
**Option A:** is incorrect because a 10-month-old child can indeed change a cube from one hand to another, demonstrating **hand-to-hand transfer**.
**Option C:** is incorrect as a 10-month-old can pull themselves to a stand, showing **gross motor skill development**.
**Option D:** is incorrect because, although their vocabulary is limited, a 10-month-old might start combining a couple of words, but expecting a sentence of 4 to 5 words might be too advanced for some.
**Option E:** is incorrect because the **pincer grasp** typically develops around 9 to 12 months, so it's on the cusp for a 10-month-old.

**Why Each Wrong Option is Incorrect (Continued)**
However, **Option B:** stands out as the correct answer because building a cube of six is a task that requires **fine motor precision** and **problem-solving skills** that are usually beyond the capabilities of a 10-month-old child.

**Clinical Pearl / High-Yield Fact**
Remember, developmental milestones can vary among children, but significant delays may indicate a need for further evaluation. The **average age** for achieving certain milestones can guide expectations but always consider the range of normal development.

**Correct Answer:** b. Can build a cube of six
