Answer 1

Correct Answer: Floccules

Rationale:

Floccules are loosely bound aggregates of particles that tend to settle rapidly but are easily redispersible upon shaking. This is a desirable characteristic in suspensions where easy redispersion is important for consistent dosing.
In pharmaceutical suspensions, flocculated particles form a network-like structure that traps liquid, leading to a loosely packed sediment that can be easily redispersed, unlike deflocculated particles that settle into a hard cake that is difficult to redisperse.

Explanation of Other Options:

Coagules

Coagules are clumped or coagulated particles that typically form a more compact and less easily redispersible sediment compared to floccules.

Defloccules

Defloccules are individual particles that settle slowly to form a hard, compact sediment, which is difficult to redisperse. They do not form a loose, easily redispersible sediment like floccules.

Sediments

Sediments are the general term for settled particles, but this term does not specify the ease of redispersibility. Sediments can be either flocculated or deflocculated.

Conclusion:

The particles that are deeply bonded, settle rapidly, and are easily redispersible are floccules. Therefore, the correct answer is option 3: Floccules.
