Question

Indented writing cannot be observed by:

• A. Naked eye
• B. ESDA
• C. Electrophoresis
• D. Microscopy

Hint:

For detecting indented writing, rely on tools like ESDA or magnification techniques, not molecular biology methods like electrophoresis.

Answer 1

The Correct Option is C

Indented writing refers to impressions left on underlying pages when pressure is applied during writing. Techniques like Electrostatic Detection Apparatus (ESDA), microscopy, and sometimes the naked eye can detect such impressions. Electrophoresis, however, is a molecular biology technique used to separate molecules like DNA or proteins and is unrelated to document examination.
