Explanation:
Most fungi are saprotroph, it is, they obtain nutrients by decomposing non-living organic matter -i.e. dead plant or animal matter- and absorbing soluble organic compounds; carbohydrates are the preferred carbon source.
A smaller percentage of fungal species are parasites, and obtain nutrients from living hosts (other living organisms).
The parent's genotypes are

and

respectively. When crossed together, all possible genotypes can be expressed. 1/4 AB blood, 1/4 A blood (heterozygous), 1/4 B blood (heterozygous) and 1/4 O blood. A Punnett square has been uploaded to support this.
The corect answer is: B. Intercalated disks.
