Explanation:

Step1: Analyze the first statement

A mixture can be separated by physical methods like filtration, evaporation etc. So the statement "A mixture cannot be separated" is false.

Step2: Analyze the second statement

Groundnut and gur (jaggery) have different physical properties (size, shape etc.). One can use hand to pick groundnut from the mixture. So the statement "You can use your hand to pick groundnut from a mixture of groundnut and gur" is true.

Step3: Analyze the third statement

Sugar dissolves in water. Once dissolved, one cannot pick sugar from the sugar - water mixture by hand. So the statement "You can use your hand to pick sugar from a mixture of sugar and water" is false.

3. B. False
