​Which of the following is a common source of energy?​

Correct option is A

The correct answer is Nuclear energy.
Explanation
Conventional Source of energy is defined as the energy sources that once exhausted, do not replenish themselves within a specific period are called conventional or non-renewable energy sources.For a long time, these energy sources have been used extensively to meet the energy demands.Nuclear energy is one of the most environmentally friendly conventional sources of energy as it produces fewer greenhouse gas emissions during the production of electricity in comparison to sources like coal power plants.

Nuclear power

• A non-renewable energy source that comes from the nucleus of atoms 
• Nuclear power plants use enriched uranium as fuel to produce electricity 
• Nuclear energy is produced through fission, when atoms split, or fusion, when atoms fuse together 

Hydroelectric power 

• A sustainable energy source that uses the energy of moving water to generate electricity
• Also known as water power, hydroelectric power has been used for thousands of years
• Hydroelectric power plants convert the kinetic or gravitational energy of water into electricity

Tidal energy

• A renewable energy source that uses the energy of ocean tides and currents 
• Tidal energy is produced by the rise and fall of tides, which is caused by the gravitational interaction between the Earth, the sun, and the moon 
• Tidal energy can be harvested using turbines and paddles 

Biomass energy 

• A renewable energy source that uses matter from recently living organisms, such as wood, agricultural residues, and organic waste
• Biomass energy can reduce reliance on fossil fuels, such as oil, gas, and coal
• Biomass energy has the potential to be carbon neutral.
