No, here is how:
anyone with an A allele will express it
same with B
O is the lack of A or B
the Rh factor only needs one allele to be expresses as well
therefore the O+ parent is OO+
the B+ parent is BB+ or BO+
therefore, they can only have a child who is B+, possible B- if they are both hertozygous for the rhesus factor, or O+/- if the B+ parent is heterozygous for B

No. O+ has neither A nor B antigens. B+ has B antigen but no A antigen. B+ can have parents who were both B or one B and one O. Their child cannot have bloodtype A+.

No. The parent with Type-O blood has the genotype 'OO', which means that he/she has no antigens on his/her blood cells, while the parent with Type-B blood has either 'BO' or 'BB', in either case meaning that he/she has only Type-B antigens on his/her blood cells. Type-A blood happens when there are Type-A antigens on the individual's blood cells, and so having a Type-A child from Type-O and Type-B parents is impossible.

No. You can be O or you can be B. Those are the only possible combinations for those blood types.
WiserAngel should talk to her parents.

no. At least one parent must have either type A or type AB to make it possible.

Yes. Both my parents are 0+ and I'm A-...inherited from an aunt.
