Hyperconjugation is best described as:a)Delocalization of p electrons ...
Hyperconjugation is the stabilising interaction that results from the interaction of the electrons in a σ-bond (usually C-H or C-C) with an adjacent empty or partially filled p-orbital or a π-orbital to give an extended molecular orbital that increases the stability of the system.

Hyperconjugation in Chemistry
Hyperconjugation is a type of chemical bonding that allows sigma electrons to interact with an adjacent empty or partially filled non-bonding p-orbital or pi orbital. The process of hyperconjugation stabilizes the system by delocalizing the electrons and reducing the energy of the system.
Explanation of the correct option
The correct option for the best description of hyperconjugation is option B. Hyperconjugation is the delocalization of sigma electrons into a nearby empty orbital. The sigma electrons are the electrons that form single bonds between atoms. When there is an adjacent empty or partially-filled non-bonding p-orbital or pi orbital, the sigma electrons can interact with these orbitals and create a bonding interaction, which stabilizes the system. This interaction is called hyperconjugation.
Other options explained
a) Delocalization of pi electrons into a nearby empty orbital: This option is incorrect because pi electrons are involved in pi bonds, which are double bonds or triple bonds. Hyperconjugation involves sigma electrons, which are involved in single bonds.
c) The effect of alkyl groups donating a small amount of electron density inductively into a carbocation: This option is incorrect because it describes the inductive effect, which is the polarization of a bond due to the electronegativity difference between the atoms. The inductive effect does not involve the delocalization of electrons.
d) The migration of a carbon or hydrogen from one carbocation to another: This option is incorrect because it describes the phenomenon of carbocation rearrangement, which involves the migration of a carbon or hydrogen from one location to another within a carbocation. This process does not involve the delocalization of electrons.
Conclusion
Hyperconjugation is a type of chemical bonding that involves the delocalization of sigma electrons into a nearby empty or partially-filled non-bonding p-orbital or pi orbital. The correct option for the best description of hyperconjugation is option B.
