Particulate data is available for what proportion of cars in the database?

Explanation:
Particulate data refers to measurements of particulate matter in vehicle emissions. In many large datasets, this data isn’t recorded for every car, so the available data forms a subset. In this database, particulate data is available for about 24% of cars, meaning roughly one in four records includes that measurement. The other options would imply far broader or far narrower coverage than what’s observed, which is less typical for PM data collection.
