Explanation:
A - Phospholipids are the most abundant lipids present in the plasma membrane of each cell.
B - While it is true that lipids are sources of energy, phospholipids do not produce energy for the cell. The mitochondria is the cell organelle which produces energy in the form of ATP for cellular processes and respiration.
C - Phospholipids are not capable of storing genetic information. The nucleus contains genetic information in the form of DNA.
D - Enzymes are responsible for increasing rate of reactions. Most enzymes are protein in nature, which is another class of macromolecules. Phospholipids are not protein in nature (they are lipids) so they do not possess enzymatic properties that allow them to increase rate of reactions.
Answer:
Characteristics of Chordata.

In some groups, some of these are present only during embryonic development.
