Okay, let's tackle this question. The user provided a scenario where a 3-year-old child has certain developmental milestones that are either met or not. The task is to determine the developmental quotient (DQ). First, I need to recall what DQ is. DQ is a measure used in pediatric development, often calculated as (mental age / chronological age) * 100. But for younger children, maybe they use different criteria based on milestones.

The child is 3 years old. Let's list the milestones mentioned. The mother says he can't walk without support, so maybe he's walking with support. Wait, the question says he can walk with support. So walking without support is not achieved yet. At 3 years, typically, a child should be walking independently. So this is a delay in motor skills.

He doesn't indicate wet pants, so he's not toilet trained. At 3 years, some children are toilet trained, but it's variable. But not being toilet trained might be a delay, but maybe not the most critical here.

He doesn't scribble, which is a fine motor skill. At 3 years, children usually start scribbling. So that's another delay. Then, he can walk with support, plays peek-a-boo, and speaks 2-3 words with meaning. Peek-a-boo is more of a younger child's game, typically around 1 year. So if a 3-year-old is still playing peek-a-boo, that's a regression or delay in social development. Speaking 2-3 words is also a delay; by 3 years, a child should have a vocabulary of about 1,000 words and use short sentences.

Now, DQ is calculated based on the developmental age. The child's developmental age would be lower than 3 years. For example, if the child is achieving milestones that are typical for a younger age, say 18 months, then DQ = (18 months / 36 months) * 100 = 50. So the DQ here would be 50. The options aren't provided, but the correct answer is likely 50.

Wait, the options were left blank. The user didn't include them. But the correct answer given is 50. So the options probably had 50 as an option. The reasoning is that the child is meeting milestones of a younger age, so the DQ is calculated as that younger age divided by chronological age.

So the key points here are the delayed motor skills (walking independently), delayed fine motor skills (scribbling), delayed language (vocabulary), and delayed social play (peek-a-boo). All these point to a developmental age lower than 3 years. Hence, the DQ is 50.

**Core Concept**
Developmental Quotient (DQ) assesses developmental progress relative to chronological age. It is calculated as (Developmental Age / Chronological Age) × 100, with DQ <70 indicating developmental delay. Key milestones like walking, language, and play are critical for age-appropriate assessment. **Why the Correct Answer is Right** The child exhibits delayed motor (walks with support, no scribbling), language (2-3 words), and social skills (plays peek-a-boo). These milestones align with a
