Fix the symbols +, -, x, ÷ appropriately in the box to fit the equation given here.
100 □ 25 □ 5 □ 5 □ 21 = 0

Correct option is B

Given:
100 □ 25 □ 5 □ 5 □ 21 = 0
From option (a) (a) -, +, ÷, x
100 – 25 + 5 ÷ 5 x 21 = 0
100 – 25 + 1 x 21 = 0
100 – 25 + 21 = 0
121 – 25 = 0
96 ≠ 0
Option (b) ÷, -, x, +
100 ÷ 25 – 5 x 5 + 21 = 0
4 – 5 x 5 + 21 = 0
4 – 25 + 21 = 0
25 – 25 = 0
0 = 0
Correct answer is (b) ÷, -, x, +.
