Fluted filter paper is used to

Explanation

The correct option here is (A) FILTER HOT SOLUTIONS.Fluted filter paper is primarily used to filter hot solutions or substances. The fluted design of the filter paper allows for a larger surface area without compromising the filtration speed. This feature is especially useful when dealing with hot solutions that may have impurities or insoluble particles that need to be removed.Let's break down why the other options are incorrect:(b) Avoid premature crystallization: As previously mentioned, fluted filter paper isn't specifically designed to prevent premature crystallization. It's primarily for filtration purposes, providing efficient separation of solids from liquids, especially in hot solutions.(c) INCREASE Rate of crystallization: Fluted filter paper doesn't have any effect on the rate of crystallization. Its purpose is filtration, not altering the kinetics of crystallization processes.
