Ficus...
Because, ficus has longest life expenditure so it has longest vegetative phase...

$$Hope you understood... $$

The correct answer is 2) Ficus.

Vegetative Phase in Organisms Life Cycle

The vegetative phase is the longest phase in an organism's life cycle. It is the phase where the organism grows and develops its vegetative structures. The vegetative phase is followed by the reproductive phase where the organism produces flowers, fruits, and seeds. The reproductive phase is usually short-lived compared to the vegetative phase.

Ficus - The Organism with Longest Vegetative Phase

Ficus is a genus of trees, shrubs, and vines. It is known for having the longest vegetative phase among all organisms. The vegetative phase of Ficus can last for several years, even up to 30 years. During this time, the Ficus plant grows and develops its stems, leaves, and roots.

The reproductive phase in Ficus is triggered by environmental cues, such as changes in temperature and humidity. When the conditions are right, the Ficus plant produces small flowers that are enclosed within a structure called the syconium. The syconium is a specialized structure that contains both male and female flowers.

Once the flowers are pollinated, the syconium matures into a fruit that is edible and attractive to animals. The animals consume the fruit and disperse the seeds, allowing the Ficus to colonize new areas.

Conclusion

In conclusion, the vegetative phase is the longest phase in an organism's life cycle. Ficus is an organism known for having the longest vegetative phase, which can last for several years. The reproductive phase in Ficus is triggered by environmental cues, and it produces small flowers that are enclosed within a structure called the syconium.
