Answer 1

Right option is (c) Release only at a specific drug

To explain: The design of delayed release systems involves the release of the drug only at a specific site in the GIT. The drugs which are included in such system are destroyed in the stomach or by intestinal enzymes. These drugs are known to gastric distress and absorbed from a specific intestinal site.
