Explanation:
Detailed explanation-1: -The correct answer is option b because a phospholipid is like a triglyceride molecule which is composed of three fatty acids bound to a glycerol backbone, except one of the end fatty acids is replaced with a phosphate group.
Detailed explanation-2: -Triglycerides contain three fatty acid molecules; but in phospholipids, one of these fatty acids is replaced by a phosphate molecule.
Detailed explanation-3: -In general, phospholipids are composed of a phosphate group, two alcohols, and one or two fatty acids. On one end of the molecule are the phosphate group and one alcohol; this end is polar, i.e., has an electric charge, and is attracted to water (hydrophilic).
