23. Which of the following statements correctly describe features and processes represented in a Jablonski energy diagram?
(A) Phosphorescence violates Kasha's Rule because it originates from the triplet state rather than the singlet state.
(B) Phosphorescence is a radiative transition from a triplet state to the ground singlet state, typically slower than fluorescence.
(C) According to Kasha's Rule, vibrational relaxation happens much faster than fluorescence.
(D) Kasha's Rule states that fluorescence typically occurs from the lowest excited singlet state $(\mathrm{S}_1)$, regardless of which higher singlet state was initially excited.
(E) Fluorescent dyes usually exhibit the Stokes shift as compared to their absorption wavelengths.
