Which haplotype carries the C and E antigens?

Explanation:
In the Rh system, haplotypes indicate which C/c and E/e antigens are present on one chromosome. To have both C and E on the same haplotype, that chromosome must carry the C allele and the E allele together. The haplotype that shows both C and E (along with D) is DCE, since it includes C and E antigens on the same chromosome. The Ce haplotype has C present but E absent, and the DCe haplotype has D, C, and e (E is not present there), while ce has neither C nor E. So only the haplotype DCE carries both C and E.
