R or real numbers are all numbers including integer and fraction (...,-4,-3,-1,0,1,2,3,4,...include the fraction)
N or natural numbers are integer numbers start from 1,2,3, and so on.
Check all of the options
∴ First option: -5 ∈ W
It's wrong, because W only contains positive numbers start from 1
∴ Second option: R ⊂ W
It's true, because R starts from 1,2,3, and so on, and it's subset from W.
∴ Third option: {0,1,2,3,..} ⊆ W
It's true
∴ Fourth option: ∅ ⊂ N
It's true, empty set is subset for all sets.
∴ Fifth option: 9 ∈ W
It's true
∴ Sixth option: W ⊂ N
It's wrong, because W has 0 but N doesn't contain 0.
The answer is second option, third option, fourth option, fifth option
