Hint: Every particle, atom and object contains some amount of energy inherent in it which gets lowered when the atom or object becomes stable. This stability can be formed due to bond formation in atoms.
Complete step by step solution:Every atom has some energy inherent in it when the atom is fixed. This amount of energy is called potential energy. Thus the hydrogen atoms have some potential energy.
The general valence shell electronic configuration of hydrogen atoms is \[1{{s}^{1}}\].Thus it contains one electron in the ns subshell. Thus it needs one electron to get the noble gas configuration and become stable.
Thus two hydrogen atoms come close and share their electrons to form a covalent bond. Thus two hydrogen atoms form a single bond and form hydrogen gas which is highly stable. So, when hydrogen gas is formed the potential energy of the individual hydrogen atoms gets lowered.
Thus the correct option is A.
Note: When a bond is formed between two atoms the potential energy gets lowered. The lost potential energy of the bond gets converted to kinetic energy. Thus during bond formation the kinetic energy of the system increases.
