I am not sure I get your question but what I make out of it is this:
When IR rises, it is better to buy a call option rather than the underlying stock since for option you need to pay less upfront. You would rather put that money in a bank and earn high interest on it. So the premium required upfront to buy a call option increases or we can say, the price of the option increases. So buyer has to pay more and seller gets more.
In the case of put option, if you are long on it, you are putting off selling the stock and getting money from it. So you are losing out on the high interest you could have got if you had sold the stock now. So the price of the put option reduces in the market i.e. you have to pay lesser premium to buy a put option. It is kind of like supply and demand. Since demand of call option increases, its price increases. Since demand of put option decreases, its price decreases.

Same way work out the logic for when IR decreases.
