Introduction to Financial Markets (405) — CBSE Class 10 board question

To dematerialise physical securities, the investor must fill a Demat Request Form (DRF), available with the Depository Participant (DP), and submit it along with the physical share certificates. A separate DRF is required for each ISIN number. The shares are then converted into electronic form and held in a demat account through depositories like NSDL or CDSL.

• Examiners expect you to mention: DRF, submission of physical certificates, separate DRF per ISIN, and the role of DP/depositories.
• Naming NSDL and CDSL adds value and may fetch full marks.
• Avoid writing about benefits of demat here — that's a different question. Stick to the process only.
