The goal is to analyze the eigenvalues and eigenvectors of this operator. The correct statement indicates that the eigenfunction of Bx can also be an eigenfunction of B^2, but not of the Y-component operator By. This highlights the relationship between different components of angular momentum in quantum mechanics."}
