Answer 1

Given series:

(Left) # * £ 3 9 € # % £ 1 % £ 8 8 1 4 9 % 5 8 & 7 (Right)

Condition to be checked:

Symbol → Number → Symbol

Let's examine the series for this pattern:

# * £ 3 9 € # % £ 1 % £ 8 8 1 4 9 % 5 8 & 7

Thus, there is only one such number (£ 1 %).

Hence, the correct answer is "Option 1".
