The question was asked by my college professor while I was bunking the class.

The query is from Biopharmaceuticals in division Biopharmaceuticals of Drug Biotechnology

Answer 1

Correct option is (b) Prolonged their residence in the GIT and release

For explanation: Delayed transit and continuous release systems are designed to prolong their residence in the GIT along with the increase of releasing time. Most of the time the dosage form is fabricated to retain in the stomach and hence the drug present therein should be stable at gastric pH.
