Answer:
The correct answer is: b).
Explanation:
- Oil or solid fat is composed of long chains made up of hydrocarbons (fatty acids).
- The fatty acid can be:
- Saturated - in which all the carbon atoms in the long hydrocarbon chain are linked to each other by single bonds. As a result of this there is a tight packing between the fatty acid molecules which gives them a solid texture at room temperature.
- Unsaturated - in which there are one or more double or triple bonds in between carbon atoms in the long hydrocarbon chain. As a result of this kinks or bends develop in the fatty acid chain which results in generation of space or gap in between fatty acid chains. This gives the fatty acid the capability to move as a result of which they have a liquid texture at room temperature.
- Hydrogenation is a process by which the unsaturated fatty acids (oil) are converted to saturated fatty acid (margarine) by reducing the multiple bonds in between the carbon atoms with hydrogen.
- Hydrogenated oil has a higher melting point and so it is solid at room temperature.
- Hydrogenated oil can also cause clogging in the arteries as they cannot be easily broken down due to their increased stability.

This
reserve is home to terrestrial and marine mammals, including grizzly
and polar bears, caribou, wolves, and wolverine as well as beluga and
bowhead whales, walrus, and several species of seals. It was
established for the purpose of preserving unique wildlife,
wilderness, and recreational values.
The
most complex level of organizational hierarchy in the Arctic National
Wildlife Refuge that is preserved is every ecosystem in the area.
I
hope it helps, Regards.
