Reserve Bank of India will soon release plastic notes in circulation will be of :

Answer: Option D

The correct answer is Option D: Rs 10 notes.
Here's why:
The Reserve Bank of India (RBI) has been planning to introduce plastic notes for some time.
Plastic notes are more durable than paper notes and are harder to counterfeit.
They also have a longer lifespan.
Initially, the RBI planned to release Rs 10 plastic notes as a pilot project.
While there might be plans for other denominations later, Rs 10 was the denomination first considered for plastic notes.
The other options (Rs 100, Rs 20, and Rs 50) are not the denominations that were initially announced for plastic notes.
