Which outcome results when doping disturbs a crystal?

A)Lattice vibrations are strongly scattered
B)Increased neutron capture cross-section occurs
C)Reduced overall material density results
D)Phonon frequencies remain virtually unchanged

💡 Explanation

Doping introduces impurities causing lattice distortion; therefore phonon transport is impeded because phonon scattering increases due to these lattice imperfections disrupting regular propagation, rather than negligible changes, neutron effects, or density shifts.
