Algin and Carrageenan are obtained respectively from-
A
Red, Red algae
B
Red, Brown algae
C
Brown, Brown algae
D
Brown, Red Algae
Explanation: 

Detailed explanation-1: –Algin is obtained from brown algae and carrageenan is obtained from red algae.-Carrageenan is present in red seaweeds. It is used to thicken a variety of foods, ice cream, salad dressings, chocolate milk, and jellies.-Algin is present in brown seaweeds.

Detailed explanation-2: -Algin is obtained from cell wall of brown algae such as Macrocystic and Fucus.

Detailed explanation-3: -Carrageenan is a water-soluble sulfated polysaccharide extracted from various species of Rhodophyta (red marine algae) and consists of long linear chains of D-galactose and D-anhydrogalactose with anionic sulfate groups (OSO3−) (Liu et al., 2015).

Detailed explanation-4: -Abstract. Algae are common all over the Earth. Due to their rich chemical composition and content of bioactive substances they have been used in many fields of industry. Their gelling, thickening and stabilizing properties have led to the development of such products as agar, alginate and carrageenan.

Detailed explanation-5: -Carrageenan is extracted from red algae (rhodophyta) and is used to bind foods together. Some examples of products that contain carrageenan are dog food, chocolate, toothpaste and baby food. Alginate comes from brown algae (phaeophyta) and is used to make water-based products thicker or creamier.
