The relationship between ionic bonds and cleavage is "as the ionic bond strength increases, cleavage will be more difficult".
There are ionic bonds between the minerals that held them together. Ionic bonds are the consequence of electrostatic fascination and electron exchange amongst positive and negative particles (cations and anions). Ionic bonding infers the development of requested crystalline solids and the cleavage of those solids will rely upon the quality of this bonding.

Explanation:
The second line of defense is a non specific defense mechanism in which no specific individual is targeted but all invaders are killed in general way. Some common mode of second line of defense are - Phagocytic cells (white blood cells), inflammatory responses, macrophage system etc. The second line of defense comes into action when the invader has surpassed the first line of defense which include either physical barrier like skin, mucous membrane, hair, cilia etc. or chemical barriers like gastric juices, saliva, Hyaluronic acid etc.
Hence, gastric juice does not belong to second line of defense.
Thus, option D is correct.
