Explanation / Answer

Please find the answers below and explanations in parentheses:

Part 1: Choice A (Bacteria are a perfect example of prokaryotes since they lack membrane bound organelles and a well defined nucleus. Along with that, bacteria carry all the genetic and cytological markers which clearly represent that they are prokaryotic in nature)

Part 2: Choice B (Hydrogen bonds are weak bonds in nature which are found either in duplicates or triplicates in the nitrogenous bases of the DNA nucleotides. These bonds originate due to partial distribution of charge upon molecueles. Similar kind of bonds are also found in water molecules. On the other hand, covalen, ionic and other interactions are strong in nature)

Part 3: Choice C (When a pair or more electrons are shared between two atoms, they complete their outermost electron shell and get stabilized. This stabilization of each atom is a highly potential event and thus forms covalent bonds. These bonds are one of the strongest kind of chemical bonds that form between two atoms)

Part 4: Choice C (Transfer of electrons takes place between those atoms which have either a few extra or a few less number of electrons than required to complete the number of electrons in their outermost shells. These are called ionic bonds. A common example is sodium chloride)
