Best answer
The correct choice is (c) b/b+ non-bald

To elaborate: Baldness is a dominant gene for a male. A bald mother is thus homozygous for the allele; at least one baldness gene will thus pass to offspring from her. The father is normal so he must lack any baldness allele and a normal gene will pass from him. Hence daughter is a heterozygote and normal.
