B Correct answer
Explanation

The uncertainty principle, fundamental to quantum mechanics, states that certain pairs of physical properties cannot both be precisely determined. Werner Heisenberg first formulated this principle in 1927, revolutionizing physics. De Broglie proposed wave-particle duality. Bohr developed atomic theory. Einstein developed relativity. Only Heisenberg is correctly associated with the uncertainty principle.
