Answer 1

As it has been stated in the question that by the economists say "there is no such thing as a free lunch",

Scarce resouces can be defined as the resources which is limited in supply relative to its demand.

It means scarce resources have alternative uses This is because in this world, it is not easy to get anything without paying anything for it either directly or indirectly. For example if you wants to eats mango from the branches of trees at free cost then you have to work hard to for getting it and the hard work is the cost which the person pay for getting mango. It means even free mango is also not free. Similary everything has alternative uses. This is the reason why

the economists say "there is no such thing as a free lunch".

Hence option C is the correct answer.

Option C; Scarce resources have alternative uses.
