The Correct Option is D

Solution and Explanation

Concept:
Hard gelatin capsule shells are made mainly from gelatin and water. The amount of water (moisture) inside the shell is very important. Too little moisture makes the shell brittle and it cracks, while too much moisture makes it soft and sticky. So a balanced amount of moisture is needed to keep the shell strong and flexible.

Step 1: Manufacturers control the equilibrium moisture content of hard gelatin shells within a specific window so that the capsules stay mechanically sound during filling, handling and storage.

Step 2: The accepted standard moisture content for hard gelatin capsule shells is in the range of about 13% to 16%. Below this the shells turn brittle, and above this they become too soft.

Answer: Option (4) — The standard moisture content range for hard gelatin capsule shells is 13–16%. (4)
