Controlled for useful work

Explanation:

Here we want to select the option that best describes what burning can be used for

Generally, when we talk about something being burnt, we are referring to the fact that we have the thing being on fire.

So basically, when something is on fire, we can say it is burning. We can harness the burning strength of a particular material or substance to do useful work.

For example, in a fire place in our homes, the burning of wood pieces can be used to heat up our homes. It is this same wood burning that has devastating effects in the bushes which in fact when left uncontrolled can cause degrees of catastrophic damages.

But, by taking the pieces and placing in a fire place in our homes, we have successfully controlled its bad effect and use it to do the useful work of heating up the environment
