Hint: Cholesterol is tetracyclic alcohol in which the alcohol is attached to the secondary carbon atom to that cyclic ring which is in the plane and it consists of only one double bond . Now identify the correct statement.
Complete step by step answer:
Cholesterol is an organic compound of a long chain of fatty acids and is a type of steroid ( these are present in the human body naturally and just like the hormones inside our body and it helps to reduce the inflammation i.e. lowers the swelling and the redness.) its molecular formula is ${{\text{C}}_{27}}{{\text{H}}_{46}}\text{O}$.
The structure of cholesterol is a tetracyclic alcohol i.e. it consists of four cyclic rings and the alcohol i.e. the -OH group is attached to that cyclic ring which is in the plane and is attached at C-3 and is secondary alcoholic group because the -OH group is attached to the secondary carbon atom and that ring is fused with the other three rings.
The four cyclic rings are not lying in the same plane i.e. they all occupy different planes and from the structure of cholesterol it is clear that it consists of only double bonds i.e. it means that there is one pi bond in the cholesterol.
So, thus from all the above given statements only statement 1. Is correct and rest all others are incorrect.
Hence, the option(D) is correct.
Note: Its functions are that it acts as a building block for the human body and helps in the production of bile too in the liver and for vitamin D too and thus, it is very essential and plays an important role in our body.
