Answer:
A
AB
Explanation:
This question involves blood type, which can either be blood type A, B, AB or O in humans. Alleles A (iA) and B (iB) are co-dominant but dominant over allele O (i).
According to this question, a mom who is heterozygous for type B blood i.e. genotype iBi, has a baby with type AB blood. Since the mother contributed the "B" allele, it means that the father contributed the A allele. Only a father with genotype: iAi or iAiA (type A) or iAiB (type AB) can produce such allele.

Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasnodesmata (channels between the cells). Each companion cell is derived from the same mother cell as its associated sieve tube member. Sieve tube members have no cell nucleus, ribosomes, or vacues. Thus, they depend on companion cells to provide proteins, ATP, and signalling molecules
