3. In reference to 4D printing and its application for tissue engineering, which of the following is not correct?

1. 4D printing involves production of complexes/structures with specific permanent shapes for potential application for tissue engineering 

2. 4D printing involves production of complexes/structures with specific dynamic shapes which may undergo morphological changes, and have potential for application for tissue engineering

3. 4D printing strategies have the potential for the fabrication of complex multilayer tissue constructs which may find applications for tissue engineering

4. 4D printing involves production of complexes/structures with specific shapes which are responsive to environmental stimuli in a preplanned way, and have potential for application for tissue engineering

Correct Answer :

4D printing involves production of complexes/structures with specific permanent shapes for potential application for tissue engineering
