As of 2020, the only person who has received the Novel Prize for physics twice is:

Correct option is A

Correct Answer Option (a): John Bardeen
Explanation:
As of 2020, John Bardeen is the only person who has received the Nobel Prize in Physics twice.

Information Booster:

First Nobel Prize (1956):
Awarded for the invention of the transistor along with William Shockley and Walter Brattain. This invention revolutionized electronics and paved the way for modern computing.

Second Nobel Prize (1972):
Awarded for the development of the theory of superconductivity, known as the BCS theory, alongside Leon Cooper and Robert Schrieffer. This theory explains how certain materials conduct electricity without resistance at extremely low temperatures.

Other Options:

• Lawrence Bragg:
  At 25, Lawrence Bragg became the youngest Nobel laureate in Physics when he, along with his father William Bragg, received the prize in 1915 for their work on X-ray crystallography.
  However, he has only won the Nobel Prize once.
  
• Arthur Ashkin:
  He was awarded the Nobel Prize in Physics in 2018 for his pioneering work in optical tweezers.
  He has only won the prize once.
  
• Marie Curie:
  Although Marie Curie is a double Nobel laureate, she won the Nobel Prize in Physics (1903) for her work on radioactivity and the Nobel Prize in Chemistry (1911) for the discovery of radium and polonium.
  She did not win the Physics prize twice.
