Answer 1

Cholesterol is a substance that is needed by the body for several functions. But the increased amount of cholesterol in the body may lead to several diseases. So it is important to control the dietary intake of cholesterol to prevent diseases.

Complete Answer:
- In our body, there are certain molecules called lipids that are water insoluble substances. They mainly are of two simple types. They are fatty acids and glycerols. Know that many lipids have both fatty acids and glycerol in them. Cholesterol is an example for a lipid substance that is useful to us in many ways.
- It is synthesised in our body by the liver. We also get cholesterol from the food we eat. Know that cholesterol performs a number of functions. It is used in synthesis of cell membrane, myelin sheath synthesis, in synthesis of several hormones, synthesis of vitamin D and several other roles inside the cell. But an increase in the level of cholesterol creates several problems in our body.
- Sunflower oil is suggested for patients having heart diseases as it contains less amount of cholesterol in it. They increase the level cholesterol that are good for our body and produces less amounts of harmful
- Cholesterol forms. Heart patients often have a high amount of cholesterol in their blood that leads to the blockage of coronary arteries. Blockage of these arteries may lead to severe heart failure and may even result in death. It decreases bad cholesterol that is harmful for us and increases the amount of good cholesterol that is good for our body.
So the assertion is correct but the reason is false as it increases good cholesterol in our body.

Hence the correct option is C.

Note: We have both good cholesterol and bad cholesterol in our body. LDL ( low density lipoproteins) are called bad cholesterol and HDL( high density lipoproteins) are called good cholesterol. Sunflower oil helps to reduce the amount of LDL and increases the amount of HDL.
