A primary metabolite is a type of metabolite, which is directly involved in the normal growth, development, reproduction of an organism. e.g. Cellulose, cholesterol, triglycerides. Secondary metabolites which are not directly involved in the growth, development. Secondary metabolite performs another function like defence. e.g. lecithin present in WBC which help in the recognition of foreign pathogen.

So, the correct answer is 'Lecithin'
