What is the primary operational difference between 'Dematerialization' and 'Rematerialization'?

[ A ]Dematerialization transfers ownership to the government, while rematerialization transfers ownership to banks.
[ B ]Dematerialization is the conversion of physical share certificates into electronic digital book-entry balances, whereas Rematerialization is the conversion of electronic securities back into physical paper certificates.[ CORRECT ]
[ C ]Dematerialization is mandatory for bank fixed deposits, while rematerialization applies to gold.
[ D ]Dematerialization occurs only on stock exchange trading floors.
Takeaway

Dematerialization converts physical paper share certificates into electronic book-entry balances in a demat account, while Rematerialization is the reverse process — converting electronic holdings back into physical certificates.

Derivation
Under the Depositories Act framework, investors submit physical certificates to their DP, which forwards them to the issuer's Registrar and Transfer Agent (RTA) for verification and cancellation before an equivalent electronic balance is credited to the investor's demat account — this is dematerialization. Rematerialization runs the process in reverse: an investor instructs their DP to convert demat holdings back into freshly printed physical certificates, a rarely-used option since physical shares cannot be traded on modern exchanges (which mandate demat settlement). The investor's beneficial ownership is unchanged throughout either conversion — only the form of the security (paper vs. electronic) changes, which is the key conceptual point tested here.
Why the others fail
A — Dematerialization transfers ownership to the government, while rematerialization transfers ownership to banks.
Ownership in both dematerialization and rematerialization remains with the same investor throughout — neither process transfers beneficial ownership to the government or to banks.
C — Dematerialization is mandatory for bank fixed deposits, while rematerialization applies to gold.
Bank fixed deposits are recorded in a bank's core banking system, entirely separate from the depository (demat) infrastructure that handles securities like shares and bonds.
D — Dematerialization occurs only on stock exchange trading floors.
Dematerialization is processed off-market through DPs and RTAs verifying and converting physical certificates; it has no connection to activity occurring on an exchange trading floor.
