Justine cruises around furniture and transfers from one piece of furniture to the next by taking one step.

She has taken one or two steps independently. How old should you guess her to be?
A. 12 months
B. 6 months
C. 18 months
D. 4 months

my answer is a.

I agree.

To determine the age of Justine based on her ability to cruise around furniture and transfer from one piece of furniture to the next, we can consider the typical developmental milestones for these skills.

Cruising around furniture usually occurs between 8 and 11 months of age when babies start to pull themselves up and use furniture for support to move from one place to another. However, taking one or two steps independently is usually achieved around 12 months or a little later.

Based on this information, it is reasonable to guess that Justine is around 12 months old. Therefore, your answer of A. 12 months seems correct.
