Which fine motor skill is characteristic of a 2 year old?

The ability to make marks with a crayon is characteristic of a 2-year-old child. At this age, children are developing their fine motor skills, which involve the use of small muscles in the hands and fingers. Making marks with a crayon shows that a child is beginning to have some control over these muscles, allowing them to engage in activities like drawing or scribbling. This marks an important developmental stage where children start to express themselves creatively, even if their marks are random at this point.

Other options, such as tying shoelaces, using a fork proficiently, or writing their name, typically require more advanced fine motor skills and coordination, which usually develop later, around ages 3 to 5. Therefore, making marks with a crayon aligns with the expected developmental milestones for a 2-year-old, making it the correct answer.
