There are no given choices so I can't exactly give the answer. However, the idea of mixing the solute and the solvent is dissolution. The goal is to achieve maximum interaction between solute and solvent to make a uniform solution. In this case, you can form intermolecular forces between the two.
I'm thinking its answer choice D. But it might be a good idea to wait and see if someone agrees
I'm pretty sure it's yards
Salt is an ionic compound NaCI. So the salt will dissolve and spread apart and the ions in the salt will move freely, letting electricity to flow freely....!
Hope i helped! If you need anything else ask me!! :)
Initially, weigh the correct amount of 
calculated from the formula.
Number of moles =
As 1 mole of is given and molar mass of is 
, then
1 mole of = 
Mass of in g = 
Thus,
1 mole of = 58.44 g.
Now, the weighed amount of i.e. 58.44 g is added to a 1 liter container and then add small amount of water in the container to dissolve the salt. After that, fill the container with distilled water to the graduation mark or until the total volume reaches 1 liter.
Thus, option (c) is correct i.e. first put one mole of salt in the container then add the water with stirring till the total volume reaches 1 liter.
