Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Nanostructures are classified by the number of dimensions that are not confined to the nanoscale.
Step 2: Classification
Zero-dimensional: quantum dots, nanoparticles.
One-dimensional: nanotubes, nanowires, fibres.
Two-dimensional: thin films, nanosheets.
Step 3: Compare the options
Quantum dot is the zero-dimensional structure.
Final Answer:
A quantum dot is a zero-dimensional nanostructure. \[ \boxed{\text{(D) }\text{Quantum dot}} \]
