Sensex vs Nifty Option Premiums Nature? [Option Selling]

Hi,

I have 4 questions-

1. Do Sensex Options generally carry a higher premium compared to Nifty? for Every strike

2. Do Sensex Options also provide a Larger range for Option selling, Like I can Sell 10-12% away? Nifty also allows that but the premiums are too low i feel.

3. Is Sensex more volatile or the same as Nifty's movements? [Charts look the same ofc]

4. What is the ratio of Sensex: Nifty? What's the easiest way to find a corresponding Sensex Level with respect to Nifty? I generally Ask Chatgpt etc.. for this.

If anyone has experience in Option Selling (Nifty and Sensex), Could you enlighten me?
