Understanding options by example

mostly I trade crypto, so wanted to dig into btc option trading, can u help?
I’ve read some general stuff about options

I want to trade it here on binance:

https://voptions.binance.com/en

1. can someone explain what is delta here and IV

2.Can we go example by example and see hypothetical situation that i buy this option

RIGHT now btc cost ~43k

Let’s say I invest $100 in option

if i buy this 44k option right now how much premium I would have to pay?

And how much money will I get if btc goes up >=44k?
