Oki
option A we have methionine which is an amino acid so the option is false.
the second option we have lecithin which is phosphatidylcholine which is false.
option C, is the correct option as I think, because both Cholesterol and Palmitic acid are both derived lipids.
option D, Co-enzyme Q is Benzoquinone, so it is false, but I dont know what dolicol is(please if you know give me a tip of it)
The last option we have amylopectin which is a polymer of glucose and one of the two constituents of starch.

So I think option C is the correct one.

Sorry it is not spelt "dolicol" it is spelt "dolichol".

Have another go.

ok this will be my last shot.
since you said option C is wrong , the only other choice that I think it is correct is B.
but I really need to review this point in my books. thank you for setting this question.

I'm sorry Adnan, but the right answer is D, because:

In Option A we have methionine which is an amino acid so that is clearly wrong.
In Option B we have lecithin which is phosphatidylcholine (a complex lipid).
In Option C we have palmitic acid which is a fatty acid
In Option D we have Co-enzyme Q and dolichol which are both polyisoprene derivatives (along with Vitamins A, K, & E)
In Option E we have amylopectin which is a carbohydrate.

Thanks for trying though.
