a. parsimony; simplest; fewest
When selecting among multiple possible phylogenetic trees that fit our data, we commonly use the principle of <u>parsimony</u>, which means we choose the <u>simplest</u> possible hypothesis. In phylogenetic analysis, that means selecting the tree that represents the <u>fewest</u> evolutionary changes or mutations.
Explanation:
Phylogeny describes the evolutionary history of on organism or group of organisms.
A phylogenetic tree structure is used to describe the relationship between various organisms which have originated from common ancestors.
The Principle of Parsimony is best applied while constructing phylogenetic tree.
This principle emphasizes on simple observations on a phylogeny which requires only few changes or variations which explain for the difference between the phylogenic sequences.
This tree structure will only have few specific genetic variations or mutations or evolutionary changes which took place through new appearance of a trait or disappearance of an existing trait.
Epithelial, muscle, connective, nerve and blood.

Analysis of a blood sample from a fasting individuals who had not eaten for 24 hours be expected to reveal high levels of glucagon .
Hence the option B is correct .
<h3>What is glucagon ?</h3>
Glucagon is on of the natural hormone of the body .it is peptide hormone.
It is produced by alpha cells of the pancreas .
It controls bodily function which include it controls the glucose level in our body .
It will release in the response to drop in blood sugar due to prolonged fast ,exercise and protein rich meals .
Hence , OPTION B is correct .
