Answer 1

(i) $False$

$\huge\bold{Reason:-}$ As we know that 5 is a prime number and in option, it is given that 5 ∉ set of prime number.(Here ∉ means does not belong to)

(ii)$False$

$\huge\bold{Reason:-}$ The set is given as {5,6,7}.Clearly, 8 does not belong to the set.(Here ∈ means belong to)

(iii)$True$

$\huge\bold{Reason:-}$Whole numbers are numbers that is more than or equal to 0. -5 is clearly less than 0. So, -5 ∉ W

(iv)$False$

$\huge\bold{Reason:-}$ $\frac{8}{11}$ is clearly a fraction and not an integer.So $\frac{8}{11}$ ∉ Z.
