Options in AFM

Dear Sir,
I have learnt that for options:

If it is an interest rate futures option:
we buy put options – if we are borrowing money
we buy call options – if we are receiving money

If it is a currency option:
we buy call option – if we are paying money in foreign currency
we buy put option – if we are receiving money in foreign currency

However, in the Question Kenduri Co, in the answer, they are buying Put options. I feel like I may have learnt wrong, if that is the case could you kindly refer me to the lectures for options so that I may clarify my misunderstanding?

I have tried understanding the answer my reading it over and over again and this is what I’ve understood – could you check if it is correct or not?
We (Kenduri) have to pay $2,400,000
But our home currency is in £
so that means we have pounds and we need to buy dollars – in order to pay the debt
that means we have to sell our pounds to dollars
therefore we buy a right to sell – we buy a put option
is my logic correct? if yes, can i apply this for all currency option questions?

Also, could you help me understand the issue in kenduri co, assuming that what i wrote above about options is correct

Thank you
