{'werner heisenberg': [0, 0, 1, 0], 'photoelectric effect': [0, 0, 2, 1], 'albert einstein': [1, 0, 4, 7], 'nobel prize': [1, 2, 6, 6], 'max planck': [0, 0, 1, 0], 'steven weinberg': [0, 0, 2, 0]}

The correct answer is option 1, Albert Einstein. Albert Einstein was awarded the Nobel Prize in Physics in 1921 for his discovery of the photoelectric effect. The photoelectric effect refers to the emission of electrons from a material when it is exposed to light or electromagnetic radiation. This groundbreaking work by Einstein provided evidence for the particle-like behavior of light and laid the foundation for the development of quantum mechanics.

Option 2, Werner Heisenberg, is incorrect. While Heisenberg made significant contributions to quantum mechanics and was awarded the Nobel Prize in Physics in 1932, it was not specifically for his work on the photoelectric effect.

Option 3, Steven Weinberg, is also incorrect. Steven Weinberg received the Nobel Prize in Physics in 1979 for his contributions to the theory of the unified weak and electromagnetic interactions.

Option 4, Max Planck, is a notable physicist who made significant contributions to the field of quantum mechanics, including the development of the Planck constant. However, he did not win the Nobel Prize for his work on the photoelectric effect.

So, the correct answer is option 1, Albert Einstein.
