Answer 2

Answer:

Option (a)

Step-by-step explanation:

Lets Analyse the options available.

(a) The set of whole numbers that are not belonging to natural numbers.

Set of Whole Numbers W = {0, 1, 2, 3, 4, 5............}

Set of Natural Numbers N = {1, 2, 3, 4, 5..........}

W - N = { 0 }

So, The set of whole numbers that are not belonging to natural numbers is a singleton set

(b) The set of vowels in the Alphabet A = {a, e, i, o, u}

Cardinality of A ≠ 1

So, set of vowels is not a singleton set.

(c) The set of natural numbers greater than 25 = {25, 26, 27, 28, 29, 30,...........}

So it, is clearly, not a singleton set.

(d) B = {x : x is a odd number }

Set B in Tabular form will be

B = {1, 3, 5, 7, 9, 11, 13..............}

Here, it most obvious that, set B has infinite number of elements, and thus, not a singleton set.

So, your answer will be option (a).
