The Nobel Prize in Physiology or Medicine was awarded to Har Gobind Khorana in 1968. He shared the prize with Marshall W. Nirenberg and Robert W. Holley for their interpretation of the genetic code and its function in protein synthesis.
Let's look at why the other options are incorrect:
C.V. Raman won the Nobel Prize in Physics in 1930 for his work on the scattering of light (Raman Effect).
Jagdish Chandra Bose made significant contributions to plant physiology and biophysics, but he did not receive the Nobel Prize.
Homi Jehangir Bhabha was a prominent Indian nuclear physicist and played a key role in the development of India's nuclear program. He was not awarded the Nobel Prize.
Therefore, the correct answer is Har Gobind Khorana.
