Answer:
Cholesterol
Explanation:
Atherosclerosis is a disease which is caused due to the formation of plaques in the blood arteries which transport the oxygenated blood to the organs.
The atherosclerosis is one of the causes of the heart attack which reduces the flow of the blood to the heart.
The plaques are formed because of the accumulation of the calcium and one of the types of lipid molecule which floats in the blood in the form of lipoproteins called cholesterol.
Thus, Cholesterol is the correct answer.

A covalent bond in which the electrons are shared unequally is called a(n) polar covalent bond. The atoms of the bond have partial negative and positive poles due to unequal electron distribution.
An electron exchange that results in the formation of electron pairs between atoms is known as a covalent bond. When atoms share electrons, a stable equilibrium of the attractive and repulsive forces between them is known as covalent bonding. These electron pairs are also known as shared pairs or bonding pairs. Since most interactions between carbon molecules include covalent bonds, covalent bonds are particularly significant. By sharing electrons with other molecules through covalent bonds, molecules can form extensive chains of compounds.
When atoms are distributed unevenly in a covalent connection, a polar covalent bond develops. Specifically, when the two atoms in the bond have electronegativities that range between 0.4 and 1.7. Polar covalent bonds and polar bonds are frequently used interchangeably.
