Question

Which of the following is not transported through a pipeline?

• A. Oil
• B. Natural Gas
• C. Biofuels
• D. Iron Ore

Answer 1

The correct option is D

Iron Ore

Explanation for correct option:

In case of option D:

1. Iron ores are rocks and minerals that can be commercially mined for metallic iron.
2. The most common forms of iron ore are hematite and magnetite.
3. Iron ores are extracted in solid form, so they can't flow through a pipeline.
4. Iron ores are transported by ships, trucks, or any means of transport.

Explanation for incorrect option:

In case of option A:

1. A nonpolar chemical compound that is predominantly made up of hydrocarbons and is both hydrophobic and lipophilic is known as an oil.
2. Oils can come from animals, plants, or petrochemicals, and they can be volatile or non-volatile.
3. Oil is usually in liquid form and its density is lesser than the density of water.
4. Oils are transported using pipelines
5. Hence it is not the correct option.

In case of option B:

1. Natural gas is a naturally occurring mixture of gaseous hydrocarbons that mostly consists of methane with traces of other higher alkanes.
2. Other hydrocarbons, such as propane, butane, pentane, and hexane, may be present in the natural gas.
3. Natural gas is present in the gaseous state.
4. Natural gas is usually transported through pipelines.
5. Hence it is not the correct option.

In case of option C:

1. Any fuel that is derived from biomass is known as biofuels.
2. Green diesel, ethanol, biogas, and butanol are some examples of biofuels.
3. Most of the biofuels are in liquified form or in the gaseous state.
4. Biofuels are transported using pipelines.
5. Hence it is an incorrect option.

Hence option D is correct.
