Solution

1) A = { $x : x$ is an odd natural number}

= {1, 3, 5, 7, 9,...........}, which is (e) in column B

2) B = Set of all squares of natural numbers, such that squares are less than 100

= {1, 4, 9, 16, 25, 36, 49, 64, 81}, which is (c) in column B

3) C = { $\frac{1}{3}$ , $\frac{2}{4}$ , $\frac{3}{5}$ , $\frac{4}{6}$ , $\frac{5}{7}$ , $\frac{6}{8}$ }

= { $\frac{1}{3}$ , $\frac{1}{2}$ , $\frac{3}{5}$ , $\frac{2}{3}$ , $\frac{5}{7}$ , $\frac{3}{4}$ }, which is (a) in column B

4) D = Set of letters of the word TRIGONOMETRY

= {G, E, I, M, N, O, R, T, Y}, which is (d) in column B
