Solution
The correct option is E a and d
Agar is extracted from Gracilaria and Gelidium. Agar is derived from polysaccharide; agarose, present in specific species of these algae. These algae are known as agarophytes and belong to phylum Rhodophyta. It is a red algae. The nature of agar is too gelatinous. Agar is actually the resulting mixture of two components: the linear polysaccharide; agarose, and a heterogeneous mixture of smaller molecules called as agaropectin.Thus, the correct answer is option E.
