So, the correct option is (c)protons & neutrons.

Because NUCLEUS=PROTONES + NEUTRONS.
& ELECTRONS just revolve around the nucleus.

1. Generally we can calculate No. of moles of solute in a solution, solution is prepared by accurately weighed W grams of solute (of gram molecular weight: GMW), transferred into V ml (say 1000 ml) standard flask, dissolved and made up to the mark with solvent
Number of moles of solute (n) =W/GMW.

2. You can find the number of moles of 1kg solvent n= 1000/GMW of solvent.
For example if you take 1kg of water, n=1000/18=55.55 moles.

Nucleus consist of nucleons and nucleons is equal to the addition of protons and neutrons.

i.e. both positively and negatively charged.

The combination of protons and neutrons has nucleus.

The atom is having three subatomic particles such as proton, neutron, electron. In atom nucleus is the central part of the atom, it consists of two subatomics i, e proton, neutron proton is having positive charge and neutron is the no charge and electron is revolution around the nucleus it is having negatively charged.
