Answer:
The correct answer is 10 to 12 years of age.
Step-by-step explanation:
Fine motor skills refer to the complex manipulation and dexterity in using groups of small muscles (Such as the muscles from the hands and fingers) to perform movements.
These types of movements require more complex cognitive mechanisms and they start developing around age 6.
At 10 to 12 years of age individuals begin to show manipulative fine motor skills similar to the abilities of adults.
In conclusion, the correct answer is 10 to 12 years of age.
