Aview of a spectacular sunset along a private beach is an example

a a private good.
b rival but nonexcludable good.
c nonrival but excludable good.
d public good.

B. NON RIVAL but EXCLUDABLE good

Explanation:

A good is Excludable if it can be feasibly prevented to be used by people , by efficiently excluding non paying consumers from using it .                                Ex: Excludable - Private Property , Non Excludable - Air Pollution

A good is Rival , if it's consumption by a consumer doesn't reduce it's availability for consumption by other consumers .                                               Ex : Rival -  Food Item , Non Rival - Voice of a Radio

A view of spectacular sunset along a private beach is :                                                    Excludable  ; because of it being 'Private'  - so can prevented to be accessed by non paying consumers                                                                                           Non Rival ; because consumption of that view by a consumer doesn't reduce its potentiality to be viewed by other people  [unless its exceptionally crowded]

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
