A fuel would be regarded as ‘environment friendly’ ifa)Its...

Answer:

An environment-friendly fuel is one that has minimal negative impact on the environment, particularly in terms of combustion and its byproducts. To determine if a fuel is environmentally friendly, we need to consider the following factors:

Calorific value:

A fuel's calorific value refers to the amount of heat energy it can produce when burned.

An environment-friendly fuel does not necessarily have a lower calorific value, as it depends on the specific requirements and efficiency of the system it is being used in.

Combustion products:

The combustion products of a fuel can have a significant impact on the environment.

An environment-friendly fuel should produce combustion products that are non-poisonous.

This means that the emissions should not contain harmful pollutants or toxins that can negatively affect air quality or human health.

Pollutants:

Environmentally friendly fuels should have minimal pollutants in their combustion products.

This means that the emissions should not contribute to air pollution or the greenhouse effect.

Examples of pollutants include carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter (PM).

Ash production:

An environment-friendly fuel should produce minimal amounts of ash during combustion.

Ash can be a byproduct of certain fuels and can pose disposal and environmental challenges.

Reducing ash production can help minimize waste and environmental impact.

Conclusion:

Based on the given options, the correct answer is B: Its combustion products are non-poisonous. This criterion aligns with the concept of an environmentally friendly fuel as it emphasizes the importance of minimizing harm to both human health and the environment.
