The correct answer is - 20 - 30 mm.

An Aggreagate is a natural or manufactured particulate material which includes crushed stone, gravel, sand, recycled concrete, and other geosynthetic aggregates. They make up to almost 60% of the concrete mix.

TIn constructions, the typical size of the aggregate used is 20mm. However in mass concrete mixtures, a larger size of almost 40mm is used more commonly.
