Solution
The correct option is AAlCl3,SO3,NO+2 Electophiles are electron deficient species. In other words, species
having a tendency to accept electrons are called electrophiles. These
may be neutral or positively charge, e.g., AlCl3,SO3,+NO2 etc.
While H2O is having lone pair so it acts as lewis base not electron defecient.(Lewis acid)
