Flocculating agent used in suspension
A
Electrolytes
B
Surfactants
C
Hydrophilic polymers
D
all tha above
Explanation: 

Detailed explanation-1: -Electrolytes are probably the most widely used flocculating agents. They act by reducing the electrical forces of repulsion between particles, thereby allowing the particles to form the loose flocs so characteristic of a flocculated suspension.

Detailed explanation-2: -The most common suspending agents are aqueous biological polymers, including methylcellulose (MC), sodium carboxymethylcellulose (CMC), and hydroxypropylmethylcellulose (HPMC).

Detailed explanation-3: -Suspending agent excipients help active pharmaceutical ingredients stay suspended in the formulation and prevent caking at the bottom of the container. One of the properties of a well-formulated suspension is that it can be easily re-suspended by the use of moderate agitation or shaking.
