State the reason why a solution is most dilute

Explanation:

Dilute solutions are prepared so as to allow a significant amount of light to pass through the solution and be measured by the recorder. Opaque solution are also diluted so light can pass through and be recorded. Similarly other substances which have very large absorption have to be diluted so that significant amount of light could reach detector.

what image you forgot to include it.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
