(C) $1$. The mother has '$B$' antibodies,which means her blood group is '$A$'. Her genotype can be either $I^A I^A$ or $I^A i$.$2$. The father has blood group '$O$',so his genotype must be $ii$.$3$. If the mother is $I^A I^A$,the cross is $I^A I^A 	imes ii$,resulting in offspring with genotype $I^A i$ (Blood group '$A$').$4$. If the mother is $I^A i$,the cross is $I^A i 	imes ii$,resulting in offspring with genotypes $I^A i$ (Blood group '$A$') and $ii$ (Blood group '$O$').$5$. Therefore,the possible blood groups for the child are '$A$' and '$O$'.
