I think that you didn't copy the answers correctly, because 1 and 2 are the same, and 3 and 4 are also the same here.
Anyways, the answer which is correct is that an electron has a charge of -1, and a proton has a charge of +1.
Electrons are negatively charged, whereas protons are positively charged. Neutrons are neutral.
I believe it is the very first one
hope it helps :)
Organic compounds are compounds that contain carbon atoms.
Organic matter is any waste product that occurs naturally (i.e. snake skin, feces, and other traces of life).
Inorganic matter would lack carbon compounds. Radioactive waste at nuclear power plants is inorganic.

An isotope is the vary of neutrons in an element, causing its atomic mass to change. While an ion is a charged atom that bonds to be stable.
