C Correct answer
Explanation

The molecule laminarin is a storage glucan found in brown algae. It is used as a carbohydrate food reserve in the same way that chrysolaminarin is used by phytoplankton. It is created by photosynthesis and is made up of Beta-1,3-(D)-glucan with Beta- 1,6-glucan linkage. This structure is quite similar to the structure of chrysolaminarin.
