Detailed Solution

The above statement is true.
Small pebbles and dirt particles can be separated from a given sample of pulses before cooking through hand-picking. Hand-picking is used to separate useful substances from undesired ones by hand. This method is useful in separating larger-sized impurities or substances easily visible to the naked eye. In addition, it can be used to separate those mixtures which differ in colour, shape or weight. The small pebbles mixed in the grains are visible to the naked eye because of their different shapes, size and colour; thus, they can be removed from the grains by hand. So, handpicking is used to separate small pebbles from grains.
