B has a smaller first ionization enthalpy than Be. Consider the following statements :I) it is easier to remove 2p electron than 2s electronII)  2p electron of B is more shielded from the nucleus by the inner core of electrons than the 2s electrons of BeIII) 2s electron has more penetration power than 2p electronIV) atomic radius of B is more than Be(atomic numberB=5,Be=4 )The correct statements are :
