Here's why:
* Subjectivity: Beauty, talent, and popularity are subjective. Different people have different preferences.
* Changing Trends: The film industry is dynamic. Popularity ebbs and flows with new releases, audience tastes, and critical reception.
* Multiple Criteria: "Number one" could be based on box office success, critical acclaim, awards, social media influence, or other factors.
Instead of trying to crown one "number one," it's more valuable to recognize the diverse talent in Bollywood and appreciate the contributions of many talented actresses.
Some of the current popular and critically acclaimed actresses include:
* Deepika Padukone
* Alia Bhatt
* Kangana Ranaut
* Taapsee Pannu
* Ananya Panday
* Sara Ali Khan
* Janhvi Kapoor
Ultimately, it's up to you to decide who you consider the best actress in Bollywood!
