Why is it useful to keep two containers of water while working with poster colour?

Answer and explanation

Correct answer: One for washing brushes and one for clean water

The governing concept is preventing colour contamination during painting. One container can receive the dirty water used to rinse the brush, while the second remains relatively clean for controlled dilution or clean mixing. This helps preserve the intended colour and prevents muddy mixtures, so option A is correct. The other options do not explain the practical purpose of two water containers and do not support clean brushwork.
