Antoinc Laurent Lavoisicr's contribution to chemistry was. a. the law of conservation of mass.
b. the law of conservation of energy.
c. the periodic table of elements.
d. the phlogiston theory of combustion.

The answer for the following question is explained below.

The option for the following answer is "d".

Explanation:

The phlogiston theory of combustion:(Greek word phlogiston means "BURN")

Phlogiston theory states that phlogisticated substances are the substances that contain  phlogiston and dephlogisticate when burned.

Dephlogisticating is the process of releasing  stored phlogiston,which is absorbed by the air.

Growing plants then absorb this phlogiston,which is why air does not spontaneously combust and also plant matte burns as well as it does.

The prevailing theory was that flammable materials contained a substance called phlogiston that was released during the combustion.

For example:

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
