Hint: Let us start answering by understanding the nature of hydrogen gas. Hydrogen gas is combustible in nature and oxygen gas supports combustion. So, when hydrogen gas burns in presence of oxygen, then some chemical reaction takes place, and that we will study further to answer the above question.
Complete step by step answer:
To start our answer, we know that hydrogen is the first element in the periodic table with atomic number 1, symbol is ‘H’ and mass is also approximately taken as 1 amu, and the most lightest element.
Hydrogen has 3 isotopes, $H^1$ (called hydrogen or protium), $H^2$ (called deuterium) and $H^3$ (called tritium). So the abundance of $H^1$ (hydrogen or protium), is very high, and so the average atomic mass is nearly 1.008 amu.
This lightest element gas is burning means it undergoes chemical reaction, and when hydrogen is burning that means it chemically combines with oxygen gas to give water with release of lots of energy.
$2{H_2} + {O_2} \to 2{H_2}O + Energy$
This huge amount of energy released is and it is due to the combustion nature of Hydrogen gas. This energy is released in the form of heat, and heat will expand gases, by making spaces between gas particles larger. Now, nearby gases in the atmosphere will gain energy and expand. In this mixture we have a mixture of hydrogen, oxygen, and water vapours, which is a product of reaction. This quick expansion in nearby gases is fast and then breaks the limit of sound frequency and reaches the hearing range values of 20 Hertz to 20 kilohertz. Thus the explosion of gases, or expansion of gases nearby will cause pop sound, and that is what we hear.
Thus, we can conclude that- Hydrogen is a gas that burns with a ‘pop’ sound, which is a given statement.
Hence the correct option is (A) true.
Note: This burning of hydrogen gas is a simple combustion chemical reaction, not any nuclear reaction. And the sound is coming just by expansion of gases due to energy of reaction, do not get confused with nuclear reactions.
Most of the other common gases like nitrogen, noble gases or Carbon dioxide, do not burn at all. Only 2 gases have such property, one is hydrogen which is combustible and oxygen supports combustion.
