N,N,2,4,6-pentamethylaniline is a stronger base than N,N,4-trimethylaniline. Why?

• A. N,N,2,4,6-pentamethylaniline is a stronger base than N,N,4-trimethylaniline because the lone pair of its nitrogen donates electron density from the benzene ring and cannot easily form bonds.
• B. N,N,2,4,6-pentamethylaniline is a stronger base than N,N,4-trimethylaniline because the lone pair of its nitrogen withdraws electron density from the benzene ring and can easily form bonds.
• C. N,N,2,4,6-pentamethylaniline is a stronger base than N,N,4-trimethylaniline because the lone pair of its nitrogen is not delocalized into the benzene ring and can easily form bonds.
• D. N,N,2,4,6-pentamethylaniline is a stronger base than N,N,4-trimethylaniline because the lone pair of its nitrogen is delocalized into the benzene ring and cannot easily form bonds.
