B. Only Statement I is true

Show ExplanationHide Explanation

Explanation

Dirac’s 1928 equation combined quantum mechanics with special relativity in a theory of the electron. Bernoulli’s equation describes idealised fluid flow, not the relativistic electron wave equation. Only Statement I is true.
