A child builds towers of 2 cubes at the age of ______
**Core Concept**
The question is related to the **developmental milestones** of a child, specifically **fine motor skills** and **cognitive development**. At different ages, children are expected to achieve certain milestones in their physical and cognitive development.
**Why the Correct Answer is Right**
Although the exact answer choice is missing, typically a child is expected to build towers of 2 cubes at around **15 months** of age. This is because at this stage, children have developed sufficient **hand-eye coordination** and **dexterity** to stack objects. The ability to build towers of cubes is a classic test of **fine motor skills** and **problem-solving abilities**.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not match the typical age for building towers of 2 cubes.
**Option B:** Similarly, this option does not align with the expected developmental milestone.
**Option C:** This option is also incorrect as it does not correspond to the age at which a child can build towers of 2 cubes.
**Option D:** Without the exact ages, it's difficult to specify why each is wrong, but typically, building towers of 2 cubes is achieved before building more complex structures.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **delayed developmental milestones** can be indicative of underlying neurological or developmental issues. Recognizing these delays is crucial for early intervention.
**Correct Answer:** D. 15 months
