Answer:
The preferable option will be - 1.
1. The fish using ventral fins as "feet" will be present in increasing numbers.
Explanation:
After many years, the fish who are using ventral fins as "feet" will be present in increasing numbers because -
We know that
- These pools are temporary pools made up of rainwater. These pools do not last for longer times.
- Some fish have developed their ability to use their ventral fin as feet and can travel from one temporary pool to others.
- So, after many years, more and more fish will develop that ability to survive.
- As we all know about "the survival of the fittest" theory so some of them won't be able to make it.
- To develop their ventral fin as their real feet will take thousands of years and some genetic modification. So, that won't happen in many years.

The change in organisms over geologic history is known as the evolution of life.
<h3>What is evolution of life?</h3>
A biological population's heritable traits change over successive generations, and this process is called evolution. At every level of biological organisation, evolutionary processes give rise to diversity. The last universal ancestor is a term used to describe the common ancestor of all life on Earth.
Modern living things are a direct descendant of extinct ancient life forms, according to evolution, which explains how living things are changing today. The majority of the time, living things improve their environmental suitability as they develop. Due to their ability to adapt, they do this.
We can solve biological issues that have a direct impact on our lives by comprehending evolution. In the world of medicine, there are many fantastic examples of this. Researchers need to be aware of the evolutionary trends of disease-causing organisms in order to stay one step ahead of pathogenic diseases.
