lanthanide `lt `actinide
lathanide = actinide
none is correct

Solution :We KNOW that, basic nature of compound, DEPENDS upon degree of DISSOCIATION, more the dossociation of compound, more the basicity. Dissociation ofcompound depends upon BOND LENGTH between metal and hydroxy group i.e. Dissociation of compound depends upon bond length betwen metal and hydroxy group i.e. M-OH. More the bond length more the dissociation.
Actinides are larger size than lanthanides. Hencxe actinides compounds are more basic than lanthnide compounds.
