Answer:
Option 2.
All of the animals undergo 23 Carnegie stages
Step-by-step explanation:
Given is a graph with four curves given for four different types of animals.
Animal 4 is the lowest of all followed by animal 3.
Animal 1 and 2 are the topmost of other 2 intersecting at a point.
Out of the four options given, I option is wrong since all animals have equal Carnegle stages.
III option is wrong since the graphs do not imply the conclusion.
IV also wrong.
Only option II is right because all of the animals undergo 23 Carnegls stages.
