Which effect occurs from reduced dimensionality affecting graphene's bands?

A)Enhanced quantum confinement effects develop
B)Thermal conductivity directly improvement rises
C)Overall structural flexibility decreases considerably
D)Chemical reactivity diminishes significantly instead

💡 Explanation

Reduced dimensionality constrains electron movement, so quantum confinement increases because these constraints raise energy state quantization in electronic bands. Therefore, the effects amplify rather than alter thermal properties which require phonons.
