Answer:
b. multicellular fungus
Explanation:
In a recent study, it was discovered that there was a genetic relationship between multicellular organisms like protozoa and animals and fungi have a common ancestor as their ancestors had contact about 1.1 billion years ago.
Therefore, the organism that was most likely the most recent common ancestor of all animals is multicellular fungus
The most recent common ancestor of all animals is option "B" which is a multicellular fungus.
In the latest research, it was discovered that multicellular organisms like protozoa and animals and fungi have a genetic relationship, share a common phylogenetic relation which means they have a common ancestor as their ancestors had contact about 1.1 billion years ago.
Phylogenetics is the study of evolutionary relationships among biological entities – often species, individuals or genes or taxa.
Thus, the multicellular fungus is the most recent common ancestor of all animals.
