D. If Assertion is false and Reason is true

Answer 1

Corrosion is a galvanic process that can be prevented through galvanizing and cathodic protection.

Step-by-step explanation:

Corrosion is the galvanic process by which metals deteriorate through oxidation. One method to prevent corrosion is through galvanizing, which involves coating the metal with a more readily oxidized metal, such as zinc. This prevents air from contacting the underlying metal and thus inhibits corrosion. Another method is cathodic protection, where sacrificial anodes are connected to the metal object, creating a galvanic cell. The anodes corrode instead of the metal object, thereby protecting it from corrosion.

In summary, corrosion is a galvanic process that can be prevented through galvanizing and cathodic protection. Galvanizing involves coating the metal with a more readily oxidized metal like zinc, while cathodic protection involves using sacrificial anodes to protect the metal from corrosion.
