Which of the following has the characteristics of a good fuel?A.CokeB.ButaneC.CoalD.Kerosene

The characteristics of a good fuel include:

1. High calorific value: This means that it should produce a large amount of heat per unit volume.
2. Easy availability: It should be readily available.
3. Easy storage and transport: It should be easy to store and transport.
4. Low cost: It should be economical.
5. Safe to handle and use: It should not pose any risk during handling and usage.
6. Low residue and pollution: It should produce a minimal amount of residue and pollution after burning.

Now, let's evaluate the options:

A. Coke: It is a form of coal and has a high calorific value. However, it is not easily available and produces a lot of smoke when burnt.

B. Butane: It is a gas that has a high calorific value and burns cleanly. However, it is not easy to store and transport.

C. Coal: It has a high calorific value and is easily available. However, it produces a lot of smoke and leaves behind a lot of residue.

D. Kerosene: It has a high calorific value, is easily available, and can be stored and transported easily. It is also relatively safe to handle and use. However, it does produce some amount of smoke and residue.

Based on these evaluations, Butane and Kerosene seem to have more characteristics of a good fuel. However, the best choice would depend on the specific requirements and constraints of the situation.
